Can I edit the main.workflow github-actions file locally?

Question

If I change my main.workflow file locally, not in the master branch, the commit and push the change, I get this error from push command:

> git diff
diff --git a/.github/main.workflow b/.github/main.workflow
index 135d8ea..0a13a28 100644
--- a/.github/main.workflow

 }

-action ".NET Core CLI" {
+action ".NET Core CLI"  {
   uses = "./.github/net-core/"
   args = "test"
 }

> git push

Still experiencing this, even with .yml workflow files. Turns out that for me it was due to me using an HTTPS remote instead of SSH.

To work around this issue in the Github API, I simply used an SSH remote instead of HTTPS.

You can see if you are using HTTPS or SSH by

$ git remote -v
> origin  https://github.com/USERNAME/REPOSITORY.git (fetch)
> origin  https://github.com/USERNAME/REPOSITORY.git (push)

Notice if there is a https:// instead of git (SSH).

Then do

git remote set-url origin git@github.com:USERNAME/REPOSITORY.git

Then verify the change

$ git remote -v
# Verify new remote URL
> origin  git@github.com:USERNAME/REPOSITORY.git (fetch)
> origin  git@github.com:USERNAME/REPOSITORY.git (push)

If you are using GitHub desktop there is currently a bug that causes this error when attempting to push commits from GitHub Actions. As a workaround, you can use the Git API until the fix for this issue is released.
