The past few days Github webhook parsing fails sometimes with errors like:
Cannot unmarshal '76058828' of type int into a string value
Cannot unmarshal '7.615998e+06' of type float64 into a string value
where the number is the commit hash’s first few characters.
This happend at the start of the pipeline, nothing is executed.
I start my investigation now, just sharing this maybe others see this too. I’m suspecting a Github format change?
Ran the tests in
src/github.com/drone/drone/remote/github with my webhook payload. The Github webhook parsing worked.
Found the error template
return fmt.Errorf("Cannot unmarshal '%v' to type %T into a string value", name, name)
I fear the error is coming form the layer where Drone tries to create Docker volumes/networks etc.
Geez, could it be that if a hash starts with numbers only something parses it as int instead of a string. Probably in libcompose.
Will keep an eye out for hashes that start with a long number sequence (without characters).
Btw, libcompose is deprecated https://github.com/docker/libcompose
I presume this is for Drone 0.8 because Drone 1.0 does not use libcompose? I would recommend upgrading to 1.0. If you can reproduce this problem in 1.0 let me know and I can investigate further.
Thanks for reply.
I think I figured it out.
The SHA variable needs to be quoted
