problems with Crowds Get User [GET] rest endpoint

When trying to request a user in groovy through the endpoint

{crowd host}/crowd/rest/usermanagement/1/user?username={username} via GET

i can't manage to get the endpoint working for me. Doing the same request using postman works though.

Documented here

Error Message:

{"message":"No content to map to Object due to end of input","status-code":500,"stack-trace":" No content to map to Object due to end of input\n\tat\n\tat

Things i tried:

Adding a body containing:

{ "name": "{username}" }
//username or user are unrecognized fields

This body leaves me with:

{"reason":"ILLEGAL_ARGUMENT","message":"An unencrypted or encrypted password must be provided exclusively."}

When adding the password into the body like so

{ "name": "{username}", "password": "{password}" }

i get:

"message":"Can not instantiate value of type [simple type, class] from JSON String; no single-String constructor/factory method (through reference chain:[\"password\"])","status-code":500,"stack-trace":" Can not instantiate value of type [simple type, class] 


But all of this is no where near what's documented in the link above. Changing around the header fields "Content-Type" and "Accept" also doesn't work. Thought it might be a xml/json problem.


But the same code with other parameters works on other endpoints fine.

I've experienced similar problems with Get direct groups

but i haven't tried as many things as on this endpoint.


P.S.: all the error messages are shortened. If you want the full error message I will post them too.
