1. Please add some context to the commit message to explain 9371dd7. It's not clear to me what this is fixing and the title seems like it's destructive. Was the workflow failure caused by the change here? If so it's not atomic so it should be combined with any fix.
2. chore commit type is reserved for changes in the repo outside of any software source code. 5c5c701 should be a fix

@rhyslbw I tidy up the commits and added a bit more context
