I got this error when working with protobuf plugin:

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

According to this https://github.com/pactflow/pact-protobuf-plugin#logging, how can I set env

LOG_LEVEL

exactly? I checked

/path/to/plugins/protobuf/log/*.log.Y-M-D

, all files are empty, and I can't see the real problem. I tried this but it doesn't work:

LOG_LEVEL=debug PACT_LOGLEVEL=trace phpunit example/async-message/consumer/tests/Contract/

This needs to be configured in the Pact-PHP integration. The default is to use the

LOG_LEVEL

environment variable, but just note that this is a Node.js/Ruby specific way. But there are FFI functions to setup the logging.

Currently in Pact-PHP I only call

pactffi_init_with_log_level('debug')

. I don't know what I am missing.

That will enable debug logs to standout, but not change the protoc error output. You can try trace to see if it makes a difference.

I did try

trace

before but it doesn't help.

I can see the protoc entries in

yes, me too, but all of them are empty

Something is going wrong with the log level then, it is meant to set the

LOG_LEVEL

for the plugin process based on what you have setup. Do you see any entries in the console for the tests?

LOG_LEVEL

ahhh, yess?? I am wondering how to do that
