NullConstraintViolationException when a call is made to OCAPI endpoint /customers/auth for JWT

[redz0701]

Hi All,
I am getting NullConstraintViolationException when trying to get JWT using
POST https://hostname:port/dw/shop/vx_x/customers/auth?client_id=xxxx
Also passing type: guest in the header.

Error:
"type": "NullConstraintViolationException",
"message": "The null value constraint for parameter 'Body' was violated. Null isn't allowed. Please provide a value."

Any help is appreciated.

Thanks in Advance.

Hi Rohit, I have tried the Customer Oauth call by adding the type: guest in the header and I am getting the same error as follows { "_v": "18.8", "fault": { "arguments": { "parameter": "Body" }, "type": "NullConstraintViolationException", "message": "The null value constraint for parameter 'Body' was violated. Null isn't allowed. Please provide a value." } } So, to get the JWT token you need to add the *type: guest* in the body of the request. Please try it and let me know. Request Body as follows: { "type" : "guest" } Regards, Anand
