Argo CD steps fail to clone the Git repository if project references an OIDC account

[flin-8]

Severity

Blocking for a small number of customers

Version

2026.2.2237, not present in 2026.2.4069

Latest Version

The problem does not exist in the latest build

What happened?

If a project references an OIDC account and running in the V2 resilient pipeline, then the Git credentials needed to clone the Git repository are not persisted, making the Git repository clone fail for Argo CD steps.

Reproduction

1. Add an Argo CD step (with valid Git credential)
2. Add an Azure OIDC account variable to the same project
3. Deploy
