Duplicate HTTP POST executions in Logic Apps despite retryPolicy = none
Severity
P1 - Critical (Blocking production)
Describe the Bug with repro steps
Expected behavior:
- The Logic App action HTTP_-_POST_PH_Time should execute exactly once per workflow run, sending a single HTTP POST request to the configured external API (PHTimeURL).
- No duplicate requests should be made when retryPolicy is set to none.
- The Logic App run history in the portal should accurately reflect all network requests made.
Actual behavior:
-
During a single Logic App run, the external API received two identical POST requests with the same request body.
-
The API (PHTimeURL) telemetry shows:
- First request started at 2025-09-15T21:01:12Z, duration ~190s.
- Second request started at 2025-09-15T21:05:44Z, duration ~120s.
-
In the Logic App portal run history:
- Only one run exists for this trigger.
- The HTTP_-_POST_PH_Time action appears only once (start 09:05:44 NZST, end 09:07:44 NZST).
- No retries are displayed, and the action is configured with "retryPolicy": { "type": "none" }.
-
Despite this, the external system confirms two POSTs occurred.
Steps to reproduce:
- Create a Logic App with the following structure:
- Trigger: When a HTTP request is received.
- Initialize array variable.
- Process payload via For_each, build up an array (TimesheetOutput).
- Final action: HTTP POST (HTTP_-_POST_PH_Time) sending the array to an external API.
- Configure HTTP action with:
"retryPolicy": {
"type": "none"
},
"runtimeConfiguration": {
"contentTransfer": {
"transferMode": "Chunked"
}
}
-
Set runAfter so the HTTP POST executes after the foreach completes (Succeeded, TimedOut, Skipped, Failed).
-
Trigger the Logic App with a payload large enough to require chunked transfer.
-
Observe:
- Only one Logic App run appears in the portal.
- The HTTP POST action appears once in the run history (with start ~4 minutes after the foreach ends).
- The target API, however, logs two POST requests with identical bodies: one at the time the foreach completed, and another at the time the portal shows the HTTP action ran.
What type of Logic App Is this happening in?
