I am getting an object from rest api into the mendix object using import mapping to show the details on screen. After updating the details on front end i want to send that object again to the rest api but when i call the update rest api then i get the below error 500:Internal Server Error. Please let me know why i am facing this issue or what can be the cause behind this error. An error has occurred while handling the request.

The REST action you are calling is returning the HTTP code 500, indicating an error occurred while that server was processing the request. You should be able to get logs from that server to understand what’s wrong with your request.

Hi,

Did you define in the header that you’re sending JSON? By default mendix api handle data as if it was XML

add this key-value pair to the header:

 

'Content-Type: application/json'
