This fixes a bug - I noticed with a colleague's blog that for whatever reason, had some null titles. XML: https://pascoal.net/index.xml

We were seeing errors in the workflow:

Error: https://pascoal.net/index.xml runner failed, please verify the configuration. Error:
Error: Cannot read response->item->title

Just gracefully handling the error so that the run can succeed.

After the fix, there are no issues:

Logs:

https://pascoal.net/index.xml runner succeeded. Post count: 80
