Failure to load extension from gitlab.com

[ghost]

Hello :sunny:

1. I'm trying to load some extensions from a gitlab.com-repository: https://gitlab.com/opvasger/tilt-extension-experiment

v1alpha1.extension_repo(name='tilt-extension-experiment', url='https://gitlab.com/opvasger/tilt-extension-experiment', ref="main")
v1alpha1.extension(name='tilt_extension', repo_name='tilt-extension-experiment', repo_path='tilt_extension')
load('ext://tilt_extension', 'vue_build', 'dotnet_build')

I'm expecting the definitions to load successfully.

What happens is that Tilt fails to load with the following error:

Loading Tiltfile at: <REDACTED>\tiltfile
Traceback (most recent call last):
  <REDACTED>\tiltfile:3:1: in <toplevel>
Error: cannot load ext://tilt_extension: loading extension repo tilt-extension-experiment: download error: waiting 5s before retrying. Original error: dynamic lookup required to find mapping

I hope you can tell me what I'm doing wrong!

Thanks for your awesome work on Tilt - it's really cool, and I appreciate you taking at look at my issue

Thanks for filing! I'm going to move this over to the core tilt repo, since this is about the extensions engine rather than a particular extension.

I'll keep the GitLab-repo open until the issue is resolved - If I can help in any way, let me know!

Thanks for working on tilt :sunny:

I had the same issue and did some digging. Seems like this error occurs when the repoRootForImportPath function in go-get fails to identify the kind of vcs system behind the URL. There are regexp cases for a few hosts like github.com but not one for gitlab. There is also a generic one if the URL ends in .git. I worked around my issues by using a .git URL and ensuring that the domain part includes a . since I had originally used a URL like https://vcs/my/repo/ and fixed it using https://vcs.my.domain/my/repo.git.

You can see the regexp here.
