In this first instalment in a series of posts focusing on head scratching errors, we will tackle the 'IndentationError' that sometimes pops up in Google Cloud Functions written in Python.
In a nutshell, if you are using 4 spaces for indentation in most of your code but then copy and paste a line with a tab in it instead, the Cloud Function deployment will result in something like the below. The error message reads IndentationError: unindent does not match any outer indentation level.
The line immediately preceding the one printed out (if request.args and 'message'...) is the culprit. Remove the tab from that line and replace it with 4 spaces. Problem solved and no more head scratching.
