Can't update theme once created

[wildhemp]

When trying to update a theme already created I get the following error:

Error: unexpected status code: 400(Bad Request) Errors: sourceThemeId: The [sourceThemeId] property should not be specified on a PATCH or PUT request. This property may only be used on a POST request.

Which makes it impossible to update the theme.

This is with version 1.47.1

I've had this same issue.

My solution was to comment out source_theme_id after the resource was created, but it would be better if this was properly fixed :)
