Hi @Mayura Wasantha , @Alexander Heinze ,

thank you for helping me :)

Now I added a custom field, persistent field string, and I would like to update this value using the following API but I’m having the following error: ODP SERVICE IS NOT ACTIVE - Service is not active.
Do you know how can be solved this?
 

Thank you!
