Data not being updated when POST request sent along with UID

[Perseus]

Steps to reproduce

Send a POST request with updated data to a URL which includes the ID
I tried to make the following URLs work:

http://localhost:8080/senaite/@@API/senaite/v1/laboratory/update/3a07aeeed03c4adeb2cafda9a4ea7854

http://localhost:8080/senaite/@@API/senaite/v1/update/3a07aeeed03c4adeb2cafda9a4ea7854

3a07aeeed03c4adeb2cafda9a4ea7854 being the UID of the laboratory object. I was attempting to update the laboratory information

Current behavior

Data isn't updated at all while trying to send data using form-data.
Data is updated when using raw json but an error "NoneType object has no attribute get" is shown

Expected behavior

Data gets updated according to the data sent in the POST request

Screenshot (optional)

As you can see in the above image, the data doesn't change.

Now, if I try to do the same as a raw request, with json only :

It updates
