Getting an error when I run `./pants generate-lockfiles`:

Engine traceback:
  in `generate-lockfiles` goal

ProcessExecutionFailure: Process 'Generate lockfile for python-default' failed with exit code 1.
stdout:

stderr:
not enough values to unpack (expected 2, got 1)

I've narrowed it down to a package that's in my

requirements.txt

as

package @ git+<https://github.com/owner/package@main>

. Is there something in that syntax I need to change, or is there something else going on?

Which version of Pants?

Yep that did it, thanks!
