push event fails due to no returned data

Line 97 in 7961b8b

await handleBaseBranchUpdate(context, eventName, eventData);

The push event handler function is only awaited and not returned. The function itself doesn't return anything anyway, so it would need to be modified to return something to fix this issue.

Since it's not returned, this causes the throw to be hit when processing a push event, since the result is undefined.

  if (Array.isArray(result)) {
    logger.info("More than one result, using  first result for action output");
    singleResult = result[0];
  } else if (result != null) {
    singleResult = result;
  } else {
    throw new Error("invalid result!");
  }

I am attempting to create pull requests to develop/staging when I merge to main, and then immediately merge all prs labeled auto-merge, but it seems like this step doesn't find all prs with the given label and merge them, it needs to be triggered by an event which would pass in the pullrequest number into the process. Is that correct or is there a way to just auto merge all the prs labeled automerge with this?

Here's what I'm trying to do atm
