Error: Failed to Stop In-Progress Sync After Trying for 60 Seconds

Issue

While modifying a connection, the Fivetran REST API returns the following error:

Failed to stop in-progress sync after trying for 60 seconds

Environment

Fivetran REST API

Resolution

To resolve this issue, pause your connection and wait until it reaches a paused state before modifying it:

1. Send a PATCH /v1/connections/{connectionId} request to pause the connection:

   {
     "paused": true
   }
   

2. Send a GET /v1/connections/{connectionId} request to check the connection status.
3. Repeat the GET /v1/connections/{connectionId} request until the response includes the following value:

   {
     "status": {
       "sync_state": "paused"
     }
   }
   

4. After the connection is paused, send the schema or configuration update request. For example: PATCH /v1/connections/{connectionId}/schemas
5. After the update request succeeds, send a PATCH /v1/connections/{connectionId} request to resume the connection:

   {
     "paused": false
   }
   

For more information, see our Connection resource.

Cause

Fivetran API tries to stop an active sync before applying connection changes. If the sync does not reach a safe cancellation point within 60 seconds, the request fails. This issue is more likely when API updates run while a sync is active, especially in automated workflows that update connections frequently.
