From Yesterday, the journey builder is not working properly and the Marketing cloud AJAX calls are responding 403, 500 errors.
Webpage :
Browser console logs :
The activities and entry sources in the journey builder are not showing up as the AJAX calls returns error.
I thought the issue may be due to the custom activity endpoint so, I updated the endpoints of the custom activity but, the problem still exists.
But, I am sure that before Yesterday, I had created the journeys even though some custom activities endpoint are invalid, It displayed the same error as in the Webpage image.
Here is the response received in the AJAX calls from the browser Network
tab :
Response 403 - { "message": "Authorization token invalid on this endpoint.", "errorcode": 40002, "documentation": "https://developer.salesforce.com/docs/atlas.en-us.mc-apis.meta/mc-apis/error-handling.htm" }
Response 500 - Error: extensions route returned 403
Anyone please help to fix this.
Thank you.
