Hi I'm trying to print/export a WebMap from ArcGIS Online through the API for Python but getting an invalid token error. I have no issue interacting with the WebMap itself, so the token should be valid. I can display the WebMap in a Jupyter Notebook, update the WebMap in a standalone script, etc.
It's only when the print line, indicated in bold below gets executed, processing starts, takes a while and then returns with the error message invalid token.
Error message in Jupyter Notebook
