Warn: Failed to get best common ancestor commit despite not configuring "UseMostCommonAncestor"

[thomasheslinbmll]

Describe the bug

I am seeing the following warning: Failed to get best common ancestor commit between source branch: <FEATURE-BRANCH> and target branch: master, defaulting to target branch commit. Error: reference not found

I can see this was introduced last week in #763, which states:

To use this option you can:

• Specify it as an env var: JF_USE_MOST_COMMON_ANCESTOR_AS_TARGET
• Specify it in Frogbot config: useMostCommonAncestorAsTarget (at Git section)

I am not seeing JF_USE_MOST_COMMON_ANCESTOR_AS_TARGET nor using useMostCommonAncestorAsTarget.

Current behavior

In my Frogbot workflow I am seeing:

I do not have a frogbot-config.yml for this repo and the Frogbot step looks like:

- uses: jfrog/frogbot@v2

    oidc-provider-name: github-dev

Same here. Any workaround in the meantime?

[thomasheslinbmll]

@ismaelhamed one option is to use v2.23.1 in the meantime.

Has anyone at JFrog taken a look at this?
