Hello! I’m trying to create a custom theme in Ignition 8.3. I see the documentation that explains the custom themes must be created through openapi but i have a problem.

I create an API key to do this an for example I use this GET CURL to get the current themes and test the API: curl -H "X-Ignition-API-Token: [token-key]" http://[myservername]:8088/data/api/v1/resources/names/com.inductiveautomation.perspective/themes but i receive error 401 unauthorized.

Can you please help me to resolve this problem?

Thank you very much!
