Interface AIRetriesExhausted

A CoTTask can automatically retry when its outputs fail validation (via CoTTask.outputDS/ CoTTask.outputFields) or when Process.beforeTaskCommit() returns errors. The retry budget is controlled by CoTTask.maxRetries and, if unset on the task, inherits from CoTProcess.maxRetries.

What happens when retries are exhausted

If every attempt fails up to the retry budget:

• No CoTTask.stateUpdates are committed.
• The process halts immediately (no fallback routing).
• Process.finished(process,lastTask,failure) is fired with lastTask set to the failing task and failure set to true.

Detecting retry exhaustion

You can observe exhaustion by implementing Process.finished() and checking the failure flag. In isolation tests that use runTask(), the same notification fires on exhaustion; the task's validation errors remain available on the task.

  isc.CoTProcess.create({
      ...
      finished : function (proc, lastTask, failure) {
          if (failure) {
              isc.logWarn("CoT halted: retries exhausted in task: " + lastTask.ID);
              // lastTask.errors contains the final validation errors
          }
      }
  });
