Http code 400 error

[LecramRed]

SOLVED
I get a 400 error when I try to connect to the Tibber API. It used to work, but not anymore.
{"errors":[{"message":"Syntax Error: Unexpected Name "This".","extensions":{"code":"GRAPHQL_PARSE_FAILED"}}],"httpCode":400,"statusCode":400,"statusMessage":"Bad Request"}

What is going wrong?

GraphQL Endpoint is https://api.tibber.com/v1-beta/gql
Token is correct (from the Tibber API explorer)

Update: I had another Cerbo which I connected to the same wifi and that worked well, while the first one still had issues. So I reverted to the normal firmware and reinstalled the Large version, and now it works fine. So there was apparently an issue with the software on the Cerbo.

Which function TibberQuery function are you calling? Can you post an example of the code? It's hard ti see what it could be without an example.

Thanks!

Thanks for you reply. It has already been solved. I had another Cerbo which I connected to the same wifi and that worked well, while the first one still had issues.
