DeleteFile action results in 404 when file exists

Start with the getContent and deleteFile calls shown in the issue, then compare their path, branch, and SHA values with the working curl request. Check how github-script version 6.4 sends these parameters. Done means deletion succeeds on my_branch or the request mismatch is isolated and documented.

Describe the bug
I am using the deleteFile action in one of my pipelines, the idea is to perform some cleanup after some tasks are successfully done. I am following the documentation of the method, I put all the required fields, but when is running I get a 404, file does not exist, even though the file is there. Is there something I am missing? when deleting using curl(same parameters) it works just fine. Unfortunately I can't share screenshots since is a private repo.

To Reproduce
Steps to reproduce the behavior:
I get the sha of the file I want to delete:

const file = await github.rest.repos.getContent({
                owner: context.repo.owner,
                repo: context.repo.repo,
                path: "${{ path1 }}/${{ path2 }}/file",
                ref: "my_branch"

and then I run the delete:

github.rest.repos.deleteFile({
                 owner: context.repo.owner,
                 repo: context.repo.repo,
                 path: "${{ path1 }}/${{ path2 }}/file",
                 message: "Delete file",
                 sha: file.data.sha,
                 branch: "my_branch"

Expected behavior
File is deleted on the specific branch.
