Start from the back of the query. Eliminate steps one by one until the error is no longer raised. (make sure to back up the query before this).
If you have no M skills yet you may want to start with (much) simpler queries.

Learn about Value.Is() , Type.Is(), and the "try ... otherwise ... " construct. Note that all these require manual typing. If you are new to Power Query then you may want to ask someone in your team with more experience to help you.
