WORKFLOW: AUTO UPLOAD CUSTOMER DATA ON FACEBOOK AUDIENCE
Describe the problem/error/question
I have tried many times to figure out how to fix this error, but I am still stuck. The HTTP node consistently encounters the same error.
I have already accepted the “Custom Audience Terms” on Facebook.
I have also checked the permissions for the Facebook API, which include all necessary permissions such as ads_management, business_management, ads_read, etc. However, it still displays the same single error report as shown below.
IMPORTANT: The strange thing is that I ran this workflow smoothly and successfully two months ago, but when I opened it today, it no longer runs
