Splunk Update User Password API Issue

[sanket]

Hello All,

We are encountering an issue with the Splunk Update Password API. When we make a request to update a user’s password, the API returns a 200 OK status code, but instead of the expected JSON response, we are receiving an HTML response. Additionally, despite the successful status code, the password is not being updated on the server.
however it was worked earlier, we have verified it's giving issue on both OnPrem and cloud instance.

splunk enterprise version: 9.3.1.0

Followed following official documentation:
https://docs.splunk.com/Documentation/Splunk/9.3.1/RESTREF/RESTaccess#authentication.2Fusers

1. Are you properly providing password and oldpassword?

2. Just for the sake of clarity - you're trying to update a local user, right?

Yes both parameters password and oldpassword are correct and yes I'm trying to update local user
