What you expected to see, versus what you actually saw

The GitHub Action ran successfully, with no errors in the logs, and there is output indicating that a pull request will be created:

However, no pull request is generated, and after some time, the action status changes to failure with the following description (the repository and organization names have been changed for privacy):

Dependabot failed to create a pull request
Dependabot ran into an issue when attempting to create the pull request

Dependabot encountered the following error:

POST https://api.github.com/repos/xxx/yyy/git/blobs: 422 - Sorry, your input was too large to process. Consider creating the blob in a local clone of the repository and then pushing it to GitHub. // See: https://docs.github.com/rest/git/blobs#create-a-blob

I have reviewed the troubleshooting documentation, but there is no information on this specific issue. Do you have any suggestions on how to debug the "creating pull request" phase in Dependabot? I have also looked into the CLI, but it seems to focus on dependency updates rather than pull request creation.
