Invalid ElementType of Vector: VariableBitWidthType (java.lang.AssertionError)

[HoneyryderChuck]

My "truffleruby on docker" CI builds are failing again:

truffleruby: an internal exception escaped out of the interpreter,
please report it to https://github.com/oracle/truffleruby/issues.

From the CI logs:

	from /home/vendor/truffleruby/21.1.0/gems/grpc-1.38.0/src/ruby/lib/grpc/grpc.rb:22:in `<top (required)>'

This appears to be the same issue/error as the GRPC error:
#2247

[eregon]

Yes, it's the same as #2247.
grpc/grpc#24632 solves this but the gprc maintainers did not merge it yet (feel free to comment there).

I'll close as duplicate of #2247, you can follow that issue.

If this error did not happen before, I guess maybe grpc was added as a new dependency?

[HoneyryderChuck]

Thx for the pointers everyone. I did browse through the issues, but didn't find a mention for this specific error.

I guess maybe grpc was added as a new dependency?

Yes indeed, I've recently added a grpc plugin to httpx, and grpc is a test dependency.

[eregon]

@HoneyryderChuck Do you think you could skip the grpc-related tests on TruffleRuby for the time being? (and also in the Gemfile, using platforms: [:mri])

[HoneyryderChuck]

sounds reasonable. will do.
