@Ujstor, I'm not sure why, but the GitHub actions are failing. Do you have any suggestions on how I can test them locally to find out why this is happening?

@sibteali786 Remove /dev/null after 'script' in the build ${{ matrix.driver }} template. Something changed in 'Script'...until now, workflows worked fine.

 - name: build ${{ matrix.driver }} template
   run: script -q  -c "go run main.go create -n ${{ matrix.driver }} -g commit -f fiber -d ${{ matrix.driver }}" /dev/null

Please do the same for all workflows, and on your push, the changed config will run in actions.

generate-linter-core.yml
