How to clear GitOps ArgoCD application cache?

Issue

• Updating .gitmodules files to new git repo location is not properly recognized by ArgoCD. The following error message can be seen:

  rpc error: code = Internal desc = Failed to checkout FETCH_HEAD: `git submodule update --init --recursive` failed exit status 1: remote: TF401019: The Git repository with name or identifier <name> does not exist or you do not have permissions for the operation you are attempting. fatal: repository <URL> not found remote: TF401019: The Git repository with name or identifier <name> does not exist or you do not have permissions for the operation you are attempting. fatal: repository <URL> not found Fetched in submodule path <path>, but it did not contain <id>. Direct fetching of that commit failed.
  

• ArgoCD caches the checkout of the application repository and it doesn't properly recognize the new location of the submodule.
