I have read the documentation, over and over and so I know the gitSource in the body is correct as it has all the required values of type, repoId and ref (I even tried with adding the sha too, which i fetch dynamically from github api)

I either get this error message: "The provided GitHub repository can't be found." or this message: "The provided GitHub repository does not contain the requested branch or commit reference. Please ensure the repository is not empty." - And i do not know why sometimes its one or the other even if the code is the same.

I know the ref is correct as the way i formatted it is how it comes back when I hit the github rest api - and the ID is correct as i've verified by looking at the source code on my github repo and seeing the id there (it is also fetched dynamically).

Here is the response code:

    const deploymentResponse = await fetch(`=${teamId}`, {
      method: "POST",
      headers: {
        Authorization: `Bearer ${vercelFullAccountApiToken}`,
        "Content-Type": "application/json"
      },
      body: JSON.stringify({
        name: branch,
        gitSource: {
          sha: gitBranchSha,
          type: "github",
          repoId: githubRepoIdString,
          ref: `refs/heads/${branch}`
        }
      })
    });

Can anyone see if there is an issue with the body or url and anything I missed?

(the sha is also fetched dynamically from said branch and is correct - although sha is not required so I can remove it and error is still same)
