Trouble Shooting Issues & their Solutions

  1. SyntaxError#2: Unexpected token b in JSON at position 0 confusing bundle ids for bundles, need to prepend with "@"

  2. RangeError: Expected "[undefined]" is same as "Interface" endo/patterns issue

  3. get E$1: undefined variable using another E import, because it gets stripped by the rollup older versions of dapps use

import { E } from '@endo/far';

the rollup intends to strip that import:

dapp-orchestration-basics/contract/rollup.config.mjs

Lines 5 to 7 in 921255e

* - import { E } from '@endo/far'
* We can strip this declaration during bundling
* since the core-eval scope includes exports of @endo/far

  1. SyntaxError: Possible HTML comment rejected at :
// ISSUE IMPORTING THIS, which promted yarn link: /* [!] (plugin

  1. possible import rejection SES check for bn.js containing while (j-- > 0) {

we can check for this from outside the container:

kubectl exec -it agoriclocal-genesis-0 -- cat ./node_modules/bn.js/lib/bn.js | grep "j\-\-"

If the file is there, we can do make copy-bn-js

ensure privateArgs adheres to the format

privateArgs: timer: (an object) - Must be a remotable TimerService, not promise

ensure to pass the result of the promise, not the promise: timer: await chainTimerService

  1. ensure to install
yarn add typescript --dev
npm install -g rollup

inspect the container, and look at the module in question:

head node_modules/@agoric/orchestration/package.json

double check the package.json version, to ensure resolution isn't overrriding a package on yarn install etc.

xsnap: v52: Error: methodGuard: guard:methodGuard: (an object) - Must match one of [{"argGuards":"[match:arrayOf]","callKind":"sync","optionalArgGuards":"[match:or]","restArgGuard":"[match:or]","returnGuard":"[match:or]"},{"argGuards":"[match:arrayOf]","callKind":"async","optionalArgGuards":"[match:or]","restArgGuard":"[match:or]","returnGuard":"[Seen]"}]

Ensure

makeAcountInvitationMaker: M.call().returns(M.promise()),

updated syntax:

makeAccountInvitationMaker: M.callWhen().returns(InvitationShape);
Cannot find file for internal module "./vat.js"

the version of @agoric/vow should be kept updated to @dev for now to keep up.

ReferenceError#1: accountsStorageNode: get E: undefined variable

Make sure privateArgs adheres to the correct shape expected or else any subsequent call to something like this will fail:

E(storageNode).makeChildNode('accounts'),
export const meta = harden({
  privateArgsShape: {
    orchestration: M.remotable('orchestration'),
    storageNode: StorageNodeShape,
    marshaller: M.remotable('marshaller'),
    timer: TimerServiceShape,
  },
});
export const privateArgsShape = meta.privateArgsShape;
Error#1: redefinition of durable kind " Durable Publish Kit "

const { makeRecorderKit } = prepareRecorderKitMakers(baggage, marshaller);

it throwing this error. provideOrchestration also calls prepareRecorderKitMakers. Also ensure the remotePowers has the following keys:

orchestrationService: remotePowers.orchestration,
timerService: remotePowers.timer,

Because makeOrchestrationFacade expects the following remotePowers structure:

/**
 *
 * @param {{
 *   zone: Zone;
 *   timerService: Remote<TimerService> | null;
 *   zcf: ZCF;
 *   storageNode: Remote<StorageNode>;
 *   orchestrationService: Remote<OrchestrationService> | null;
 *   localchain: Remote<LocalChain>;
 * }} powers
TypeError: orchestrate: no function

If i log asyncFlowTools:

2024-06-30T02:33:01.781Z SwingSet: vat: v38: { prepareAsyncFlowKit: [Function: prepareAsyncFlowKit], asyncFlow: [Function: asyncFlow], adminAsyncFlow: Object [Alleged: AdminAsyncFlow] {}, allWokenP: Promise [Promise] {} }

{
  "name": "@agoric/async-flow",
  "version": "0.1.1-upgrade-16-fi-dev-8879538.0+8879538",

this is the orchestrate function in @agoric/orchestration@0.1.1-upgrade-16-fi-dev-8879538.0+8879538

orchestrate(durableName, ctx, fn) {
    /** @type {Orchestrator} */
    const orc = {
    async getChain(name) {
        if (name === 'agoric') {
        return makeLocalChainFacade(localchain);
        }
        return makeRemoteChainFacade(name);
    },
    makeLocalAccount() {
        return E(localchain).makeAccount();
    },
    getBrandInfo: anyVal,
    asAmount: anyVal,
    };
    return async (...args) => fn(orc, ctx, ...args);
},

Here is the same orchestrate function in @agoric/orchestration@00.1.1-dev-6bc363b.0+6bc363b:

orchestrate(durableName, hostCtx, guestFn) {
    const subZone = zone.subZone(durableName);
    const hostOrc = makeOrchestrator();
    const [wrappedOrc, wrappedCtx] = prepareEndowment(subZone, 'endowments', [
    hostOrc,
    hostCtx,
    ]);
    const hostFn = asyncFlow(subZone, 'asyncFlow', guestFn);
    const orcFn = (...args) =>
    // TODO remove the `when` after fixing the return type
    // to `Vow<HostReturn>`
    when(hostFn(wrappedOrc, wrappedCtx, ...args));
    return harden(orcFn);
},

Hypothesis: prepareEndowment doesn't exist, so version issue

  1. If you see x.js can't be resolved from an @agoric/... npm package, there may be a version mismatch where that version isn't exporting said file. Should be fixed with more stable versions eventually.

Error#1: In "makeAccountInvitation" method of (OrcaFacet): result: (an object) - Must be a remotable Invitation, not promise

ensure your public facet returns the result of a promise, not the promise:

const publicFacet = zone.exo(
  'OrcaFacet',
  M.interface('OrcaFacet', {
    makeAccountInvitation: M.call().returns(M.promise()),
  }),
  {
    async makeAccountInvitation() {
      // make sure NOT to use async here
      const invitation = await zcf.makeInvitation(
        createAccounts,
        'Create accounts',
        undefined,
        harden({
          give: {},
          want: {},
          exit: M.any(),
        }),
      );
      return invitation;
    },
  },
);
2024-07-01T19:16:10.669Z SwingSet: vat: v104: Warning for now: vow expected, not promise Promise [Promise] {} (Error#1)

Make sure the offer handlers are in the top-level scope, so they don't inherit any "side effects"

await makeAccountInvitation() {

instead of:

makeAccountInvitation() {

also the function signature that works is:

/**
 * handler function for creating and managing accounts //* Xparam {object} offerArgs
 * @param {Orchestrator} orch
 * @param {undefined} _ctx
 * @param {ZCFSeat} seat
 * @param {{ chainName: string }} offerArgs
 */
const createAccountsFn = async (orch, _ctx, seat, {chainName}) => {```

some types were not correct

Then also, fron the client:

wallet?.makeOffer(
    {
      source: 'contract',
      instance,
      publicInvitationMaker: 'makeOrchAccountInvitation',
      // publicInvitationMaker: 'makeAccountInvitation',
      // source: 'agoricContract',
      // instancePath: ['basicFlows'],
      // callPipe: [['makeOrchAccountInvitation']],
    },
    { give, want },
    { chainName: "osmosis"},

The offerArgs was empty

noble/hashes

Dapps keep hitting this because registry uses starshipjs:

import { useRegistry, useChain, ConfigContext } from 'starshipjs';

the error says:

AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

reproducable here

> await import("starshipjs");
> Uncaught:
> Error: Cannot find module 'dapp-orchestration-basics/node_modules/@noble/hashes/sha256.js'

steps to try to fix

Issue is sha256.ts exists, so we could just generate the js from it:

cd node_modules/@noble; npx tsc --init; npm install @noble/hashes; npx tsc; yarn; npm run build

then clean and try again

yarn cache clean; rm -rf -v node_modules ui/node_modules contract/node_modules; yarn cache clean; yarn

HTTP body

this one reared its ugly head again after a while: Error: error in json rpc client, with http response metadata: (Status: 400 Bad Request, Protocol HTTP/1.1). RPC error -32600 - Invalid Request: error reading request body: http: request body too large

remember we talked about maybe increasing the allowed body length or something..

hit when, maybe bundle grew:

kubectl exec -i agoriclocal-genesis-0 -c validator --tty=false -- agd tx swingset install-bundle @/tmp/contracts/b1-43c74d8a4bb5aa82267ba7a35b79eb3fe82e20f57f6ca9533df052f23fd30aada19478c7e61e078c81594699a190eb327119bce5b33d2d9bd0e8a58971aac387.json --gas auto --keyring-backend test --chain-id agoriclocal --from agoric1hm54wrxsv8e3pnw6lxj5lssfpexn48xtj6fhxw --broadcast-mode block --gas auto --gas-adjustment 1.4 --yes --output json

solutions

  1. revert this lines back inside multichain-testing update-config.sh:
echo "Increase $(*_bytes) parameters for MsgInstallBundle"

  1. Attempt to reduce bundle size by dedup, and removing comments
