Connecting Airtable to PowerBI - Error message - Null value

Hello everyone,

I followed the following tutorial (https://support.airtable.com/docs/visualizing-airtable-records-in-microsoft-power-bi-power-query) to connect Airtable to PowerBI Desktop.

I followed each step as required, my IDs are all correct, I even went to GitHub to grab the latest updated code. I also modified the authentification system as the tutorial explains it.

However, it doesn't work and I get the following error message: "Sorry, we were unable to convert the null value to Record type."

Could you please tell me what the problem is? I've looked at other requests on the forum and it seems to me that nobody has had a real solution?

Thanks for your feedback,

Have a nice day,
