Fetching a module from a branch with / is broken when github.com us the source

[lazzurs]

When using github.com as a source for a module in a sub directory the following works.

source = "github.com/xxx/infrastructure-modules//dev-dns-zone?ref=v0.0.1"

But this does not.

source = "github.com/xxx/infrastructure-modules//dev-dns-zone?ref=feat/PTP-1841"

The first version will run apply and plan as expected. The second version brings the following error.

`ERRO[0001] 1 error occurred:
* error downloading 'https://github.com/xxx/infrastructure-modules.git?ref=feat': /opt/homebrew/bin/git exited with 1: error: pathspec 'feat' did not match any file(s) known to git

ERRO[0001] Unable to determine underlying exit code, so Terragrunt will exit with error code 1`

Something appears to be removing the / from the branch name.

Further testing has shown the following does work

  source = "git::git@github.com:xxx/infrastructure-modules//dev-dns-zone?ref=feat/PTP-1841"

For now we can switch to this but the original version should work.

Hey @lazzurs + @kamranrana-hi ,

As mentioned in the linked PR closing this issue, there's a quick workaround available by escaping / with the hex code %2F. Added a test so that we can reliably reproduce this guidance in the future.

Let me know if that helps!
