This simple sample demonstrates how to execute a workflow that, upon encountering a failure, notifies a user so that they might correct the erroneous input.
Start local dev server as: temporal server start-dev
Then in another terminal start the worker: go run cmd/backend/main.go
Finally issue these commands to spoof a failure: )
# start the workflow with a bad SubscriptionID of "GarbageSubscriptionID"
temporal workflow start --type OnboardApplication \
--workflow-id foo \
--input-file onboard_application.json \
--task-queue apps
# observe that:
# 1. the "SetupJFrog" activity has failed due to having this SubscriptionID
# 2. the workflow detects this BadSubscriptionIDErr so RequestsCorrection
# send a signal to the workflow to correct the bad SubscriptionID
temporal workflow signal --name correctSubscriptionID \
--input '{"subscriptionId": "123"}'
--workflow-id foo
# observe that the workflow re-calls the SetupJFrog activity and exits
