BeyondImporter_5eOGL not working anymore

Hi, firstly thanks for all your efforts.
I just tried the BeyondImporter_5eOGL script to import some DnD beyond chars into roll20. However the script fails, I believe due to the json having a new syntax. I had to change the version number in the json retrieval web address to v5 instead of v3 to even get an output.
Hoping this is not abandoned. Thank you!
