Add concurrency control to Audit Log CSV import flow

[Copilot]

Flow "Admin | Audit Logs | Load events from exported Audit Log CSV file" fails with "The response is not in a JSON format" when processing ~33k row CSVs. Unlimited parallel foreach operations exceed Power Automate response limits.

Changes

• Added runtimeConfiguration.concurrency.repetitions: 25 to LoopFileRows foreach loop
• Limits parallel CSV row processing to match pattern used in AdminAuditLogsSyncAuditLogsV2 flow

File modified: AdminAuditLogsLoadeventsfromexportedAuditLogCSVfil-A6875DF5-55E8-ED11-A7C6-002248081470.json

               "metadata": {
                 "operationMetadataId": "f3a0f35b-278e-446e-bfec-39654d6ea90e"
               },
-              "type": "Foreach"
+              "type": "Foreach",
+              "runtimeConfiguration": {
+                "concurrency": {
+                  "repetitions": 25
+                }
+              }
             }

Allows large audit log CSV imports to complete without triggering response format errors.

Describe the issue

When I upload the CSV file and run the flow, I receive the following error. The CSV contains about 33,000 rows, which does not exceed the 50,000-row limit. Other flows are working without any issues. 4.50.8 / 4.50.7 Both versions have the same error.

<agent_instructions>Investigate why the flow Admin | Audit Logs | Load events from exported Audit Log CSV file fails with ‘The response is not in a JSON format’ when importing a ~33k‑row CSV in Core v4.50.7/4.50.8. Other flows work. Check CSV parsing, file handling, large row processing, or any malformed rows causing the flow to return a non‑JSON response. Provide the fix so large audit CSV uploads run successfully.</agent_instructions>
