pollStatus

Polls for the challenge status and emits the current polling status.

This method returns a Flow that emits PollingStatus updates throughout the polling lifecycle. The polling behavior depends on the configuration set during init:

Challenge Status Polling Mode

When pollChallengeStatus is true and challenge is not empty:

1. Extracts configuration from continueNode.input:

• _links.next.href: Used to construct base URL

• interactionId: Required header for polling requests

2. Constructs polling URL: {baseUrl}/davinci/user/credentials/challenge/{challenge}/status

3. Polling loop (repeats up to pollRetries times):

• Delays for pollInterval milliseconds

• Makes HTTP POST request with interactionId header

• Parses JSON response for isChallengeComplete field

• If HTTP error (status ≠ 200): Emits PollingStatus.Expired and stops polling

• If challenge complete: Emits PollingStatus.Complete with server status and exits

• If not complete: Emits PollingStatus.Continue and continues polling

• If exception occurs: Emits PollingStatus.Error and exits

4. If max retries reached: Emits PollingStatus.TimedOut

5. If configuration missing: Emits PollingStatus.Error immediately

Simple Polling Mode

When pollChallengeStatus is false or challenge is empty:

1. Validates pollInterval (must be 0)

2. Delays for pollInterval milliseconds

3. Decrements retriesAllowed

4. If retries remain: Emits PollingStatus.Continue with remaining retries

5. If retries exhausted: Emits PollingStatus.TimedOut

6. If invalid interval: Emits PollingStatus.Error

Flow Interception

After emission but before the caller receives it, the flow uses onEach to set the value property based on the emitted status:
