Finally it's fixed! (must protect null parameters)
I made some queries on graphql to retrieve the ids of the stations that were causing the problem. To set null to "0".

sorry for my english i am french i use google translate...

@Ondřej-Šutera I may have made mistakes with your API too...

@Ondřej-Šutera Yes, that doesn't work either. But it works with another account. I think there is a problem with my account. I have a lot of stations on my account (around 500 I think).

Hello I cannot access: https://stations.windy.com/stations
I have an infinite loop...

It works on another account

Thank you for your help.
