The JSON API is not reachable. 500

Hello,

I take the liberty of contacting you as I have a huge bug that appeared when I checked (to test) an option in the settings of Sprout.

Following that an error message appeared in my invoices. It was then that I realized the extent of the bug.

Considering my low level in wordpress, I don’t understand where the problem is coming from.

Can you help me ?

Here is what wordpress returns to me:
