Hi Experts,

I have changed the credential type to NavUserPassword in my 2019 version Business Central.

But after completing all the steps mentioned here, I'm getting the following error in the web client. Please help me

I have changed in the ClientServicesCredentialType to NavUserPassword in navsettings.json file but still getting this error.
