Json query error internal server error 500

[grafanausername]

Hello, I am currently trying to display data from a server using its API.

To display the data, the service provider has indicated in the docs that an “Authorization” header in base 64 must be used for authentication,

When I do the tests in Postman, I can display the data and when I test from the terminal of the grafana server with Curl -H “Authorization …” I can also display the data

but when I try to display the data in a Grafana dashboard, I get the following error

I saw that other people had the problem but I did not manage to solve my problem with the content of their topic,

Thanks for your answers
