error: KeyError: 'Version'

[ethanquix]

Describe the bug
When running pants tailor :: I have this error message:

❯ pants tailor ::
14:39:18.16 [INFO] Initialization options changed: reinitializing scheduler...
14:39:24.10 [INFO] Scheduler initialized.
14:39:28.41 [ERROR] 1 Exception encountered:

Engine traceback:
  in `tailor` goal

KeyError: 'Version'

Pants version
2.16.0

OS
MacOS

Additional info
Here is my pants.toml:

[GLOBAL]
pants_version = "2.16.0"

backend_packages = [
    "pants.backend.experimental.go",
    "pants.backend.python",
]

[golang]
minimum_expected_version = "1.20"

The first pants tailor :: works, but if I run it again I have this issue.

It happens also when I run other commands like:

❯ pants list ::
14:55:53.45 [ERROR] 1 Exception encountered:

Engine traceback:
  in `list` goal
  in Find targets from input specs

KeyError: 'Version'

Thanks for the bug report! Would you be able to post (a simplified and redacted) version of the repo that reproduces this?

[benjyw]

And also, can you run with --print-stacktrace so we can get a full stacktrace for that error?

This is something I experience myself in a repo that has in a go.mod file

replace company.org/packageA => ../common/packageA

replace company.org/packageB => ../common/packageB

require (
	company.org/packageA v1.2.3
	company.org/packageB v1.2.3
        ...
)

Removing those sections let Pants proceed.

@ethanquix are you able to interact with our https://github.com/pantsbuild/example-golang repository?

I'm running into the same issue in my repo using pants. Using replace is added to use the proto code generated by pants (under dist/) and there's no way around this unfortunately. @benjyw, let me know if I can help debug the issue with logs, etc.

Hi @wslulciuc , as mentioned earlier, the best way to facilitate debugging is to create a small public repo on github that recreates the issue.

@ethanquix Is your project making use of the replace directive in a go.mod file? If so, it looks like this would be an instance of #14996
