PUT Robot Request

when migrating from version 2020.10.15 to 2023.4.3 I am experiencing a problem with updating certain values (username and password) in a robot that has already been created and is in the relevant folder.
Below is the json used so far with the old version:


The error found is as follows:

Robot does not exist

Is the syntax correct or should I take into account changes due to the change from classic to modern folders?
Thanks in advance.


The key would have changed once you migrate from classic to modern can you check the same
