What’s the right way to mask PII in Architect context before the recording storage pulls it? Running GC v23.8.2 in eu-central-1, the wf_security_pii_mask_v2 flow throws a 403 Forbidden with INVALID_CONTEXT_PERMISSION on POST /api/v2/recordings/storage. In CIC we used to just toggle the encryption flag on the recording server, but the endpoint docs don’t show a masking parameter and the logs just show the context object getting dropped entirely after the Set Variable step.
The INVALID_CONTEXT_PERMISSION error happens when the flow token tries to override recording server settings. Docs state “context tokens are bound to the originating flow and cannot be reused across different recording storage calls.” You don’t actually POST to /api/v2/recordings/storage to mask PII. That endpoint expects a valid context token and raw audio metadata.
Sanitize the data in the flow before the recording starts. Use a Set Data action with a replace expression:
replace(contact.phoneNumber, "[0-9]{3}-[0-9]{3}-", "***-***-")
Pass the sanitized variable into the recording context using set recording context. The recording server will pull whatever is in the context at that exact moment. If you keep hitting 403s, check the OAuth client credentials. It needs recording:write and interaction:write. The CIC encryption toggle you mentioned got deprecated in v22.4.
Also, the context object drops when the flow times out waiting for the recording server callback. Add a timeout handler to the action and set it to 30s. Docs state “data actions must complete within the configured timeout or the context is cleared.” Try stripping the raw context payload down to just the masked fields. Extra keys trigger validation failures on the storage endpoint. Expression syntax is strict here too. Make sure the doesn’t have unescaped brackets. It’ll throw a syntax error and skip the masking step entirely.
