Getting a typeError when running `truffle test` after update

Coming back from vacations, I just updated my truffle install from v5.1.4 to v5.1.7.

When running truffle tests (that used to work) I’m now getting:

  "before all" hook: prepare suite:

[Amxx]

Using 5.1.4 was ok for now, but it’s looking like it’s not going to support my transition to ^0.6.0.

@gnidan The code that triggers that is not public, but I could send you an archive with it

[haltman-at]

Well, I mentioned it to them on their Gitter, but I didn’t open an issue because I’d be missing one key thing: A reproduction example! (I couldn’t use Amxx’s because his was sent to us privately.) So, it would be better if you could open the issue. But if you have a reproduction example, I suppose I could do it.

As for telling the two errors apart… yeah, they don’t really belong in the same thread; sometimes unrelated errors just end up grouped like that. 😕 They don’t actually resemble each other, just the new error message (from the ID clash) never got posted here because some of this discussion was conducted with Amxx in email.

The error that resulted from the ID clash – copying it in from Amxx’s email – looked like this:

     TypeError: Cannot read property 'find' of undefined

So, if you were getting the first of these errors, rather than the second, it’s more likely a bad ABI.

Anyway, I would encourage you to submit the issue yourself (or @Amxx, I would still encourage you to do so, with both issues!) but if you can send us a reproduction example I might have time to inspect it and submit the issue.
