@Alsalahi, Zakarya - Vendor Looks like there is an issue with your workflow and saving your workflow doesn't show the actual error message. Can you navigate to the developer tools (F12) --> Network and start recording the network logs. Reproduce the issue and verify if you are able to see any 400 requests when you execute your timmer trigger workflow. The 400 requests should return the actual error from the backend service. If you are not able to find the cause then please open a support ticket with us and if you don't have the support plan then please refer to my private comment to assist you further.
