Error when inserting customers [ Trying to access array offset on value of type null ]

[EspaceEnjo]

I have a problem. I am trying to insert a customer via the webservices but an error keeps occurring.

"This call to PrestaShop Web Services failed and returned an HTTP status of 500. That means: Internal Server Error."

My PrestaShop is hosted locally on Docker. I've been trying to fix this problem for 2 days now, but it's impossible. Moreover I can't find any solution online. Can you help me, it would be great!

 

When i go to "/api/customers?schema=blank"

 

Have a nice day, Mick.
