Metadata could not be deserialized

[musi00]

Hello,

I have a provider connector up and running and I'm trying to get the description of the resource via the REST API: /admin/api/request/description. However this fails with the error: "Metadata could not be deserialized". I can successfully get the description of the connector (i.e when I leave the resource-id field blank) but it fails when I use the resource-id.
I can also get the resource description successfully via the Resrouce Handling API: /admin/api/resources/{resource-id}.

Here is a screenshot of the Failed API Request:

I actually have 2 connectors setup (provider and consumer) and consumer has to be able to get the description of the resource in order to negotiate the contract as discussed in the wiki. However I get the same error when I do it from the consumer side. The above error happens from the provider side (i.e the connector is getting the description of its own resource, this was done for debugging).

Hi! The id you are requesting is wrong. Within the connector's self-description, each resource has an id like that: "@id" : "https://w3id.org/idsa/autogen/resource/0573bfc3-4627-4c73-a0db-54745e120485",. You have to request this one.

Hi Julia, thank you for your reply. I corrected the id but I still get the same error:

What version do you use?

v4.0.2

I tried again with v4.1.0 and this time it worked. Also when requesting the artifact from the consumer side, the representation id must be used to negotiate the contract and then this same representation id must be used to request the artifact after the transfer contract URI is provided. I was trying to use the resource id initially and that didn't work. Just in case someone else ran into a similar issue.
