The problem with aggregate error is that it accepts pretty much anything, so if you push an array of logger errors then it looks like this:

Meniole/plugin-template#1 (comment)

Corresponding code:

  throw new AggregateError([new Error("error 1"), new Error("error 2"), logger.error("logger error"), new RangeError("range error")]);

But I think it would be the logger responsibility to properly handle toString() method so it doesn't display this way.

@whilefoo using the same code snippet in mentioned before, I pulled the latest version and now it seems to look like:

Am I missing something? I cleaned lock files and node_modules to be sure, same result.

Works for me: ubiquibot-whilefoo-testing/testing#19 (comment)
Did you run sdk:build?

@gentlementlegen okay to merge?

[gentlementlegen]

@whilefoo Oops sorry forgot to test again, will give it another go and merge if it goes well.

Seems to work fine, thank you for the fix and sorry for the delay, might have been some residue in my node_modules files.
