Smells like CORS.

The "UntrustedHost" error indicates that the host you're trying to connect to is not recognized as a trusted host. To resolve this, you need to add the host to your list of trusted hosts in your application's configuration.

Here's a general approach to fix this:

1. Identify the Configuration File: Locate the configuration file where your application defines trusted hosts. This is often found in settings or environment configuration files.

2. Add the Host: Add expenserepo.com to the list of trusted hosts. This might look something like this in a configuration file:

   "trustedHosts": ["expenserepo.com"]

3. Restart Your Application: After making changes, restart your application to apply the new configuration.

For more detailed guidance, you might want to check the documentation specific to the framework or library you're using for authentication. If you need further assistance, feel free to provide more details about your setup.
