SyntaxError: invalid syntax

Answer 1

You have to just replace "," by "as"

except RuntimeError as e:
      # Your Code

Answer 2

I just fixed the problem, I hope to help someone to save time since I lost hours today.

Basically, you just need to replace ".geojson" with ".json" (without changing the file extension).

I do not understand why, and if you have the answer please let me now, but now it works.
