Any idea on this?

2022-12-07T21:16:20.081180Z ERROR ThreadId(01) pact_ffi::plugins: Failed to call out to plugin - Request to configure interaction failed: Failed to process protobuf: Failed to invoke protoc binary: exit code exit status: 1

It is available:

$ which protoc
/usr/local/bin/protoc

The protoc binary exited with an error code. It should have printed out an error message, which will be in the logs

Here is the full output I have on my console:

$ go test -v .

Ok, what OS are you running? Is this running in Docker?

Ringo - could please check the logs of the protobuf plugin to see if anything else is in there? It should be

~/.pact/plugins/protobuf-0.1.xxx/log/plugin.log.*

@Matt (pactflow.io / pact-js / pact-go) only two lines in the log file:

2022-12-08T07:19:42.612162Z ERROR tokio-runtime-worker pact_protobuf_plugin::server: Failed to process protobuf: Failed to invoke protoc binary: exit code exit status: 1

If you enable TRACE level logging, it will print out the command it is trying to execute

I’ve noticed a bug in the way logging is handled in Go - having to set an env var and use

SetLogLevel

is not the intention, I’ll fix that shortly.

Where/how should I configure the TRACE level logging? Any pointer to a doc page describing that?

Just on the go but I'll push up a fix tonight. Exporting the following should work though:

export LOG_LEVEL=trace

(I think it's currently mentioned in the troubleshooting guide)

Found the problem:

The main protobuf file in

./proto/pulumi/language.go

imports

pulumi/plugin.proto

, but to resolve this correctly, I need to be able to configure the include path from

"-I/Users/ringods/Projects/pulumi/pulumi-pact-poc/proto/pulumi"

to just

"-I/Users/ringods/Projects/pulumi/pulumi-pact-poc/proto"

(e.g. drop the last part

pulumi

from the path. Can I do that?

You can add additional includes in the plugin manifest file, under

pluginConfig

, see https://github.com/pactflow/pact-protobuf-plugin#configuration

@uglyog that’s good for now. IMO this should be a project-level configuration though.

FYI have created https://github.com/pactflow/pact-protobuf-plugin/issues/17 to track this. I got a similar feedback from another user via a DM last week

Thanks for this. I upgraded to pact-protobuf-plugin v0.2.4.
