Quickstart: Verify an Output Converter

Register a converter

Follow the complete implementation and registration example in Output Converters. Create a deterministic converter that turns a sample object into text, declare source/result types and a settings schema, and register it with a stable ID through the public service-registration extension.

Author a workflow

Add a string variable or workflow output.
Bind an activity's sample-object output to that destination.
Select the registered converter.
Configure its formatting setting.
Save and reopen the workflow.

Execute

Run the workflow and verify:

The bound variable/workflow output contains the converted text.
The activity output register and journal contain the original sample object.
The converter resolves from the workflow scope.
Replaying the same assignment produces the same Bound Value.

Exercise failures

Verify definition rejection for an unknown ID, incompatible destination, and invalid settings. Then remove the registration after publishing and execute the definition:

The activity faults through normal fault handling.
The destination remains unchanged.
The native Activity Output remains available.
Persisted exception metadata identifies the converter, activity, output, destination, and resolution stage.
The default message contains neither the native value nor raw settings.

Verify backward compatibility

Execute and serialize a workflow with no converter configuration:

JSON omits the converter object.
Existing output assignment tests remain unchanged.
Instrumentation observes no converter registry lookup.
