Porting a third party TF provider and its failing with

$ pulumi preview -v=10

...

error: an unhandled error occurred: Program exited with non-zero exit code: -1

. Is there way to see the output from the provider binary?

Try `TF_LOG=TRACE`to get logging from the TF provider itself? (This is noted at the end of https://www.pulumi.com/docs/troubleshooting/#verbose-logging).

Thanks, digging into it
