Architect Data variables not rendering in Text-to-Speech

[Duncan_Stewart]

I'm building a call flow integration w/ Salesforce, and I'm trying to use some of the flow variables in an audio sequence. I can verify that the variables are populated, as I can output them as text data, but when I try to output them as TTS audio, there's no response.

[08.12.22 - Duncan - hold please; researching data retrieval more closely...(ignore what follows, for now)]

Here's the text output, which renders correctly: "Patient Cycler Schema found: Cycler s/n: " + Task.CyclerSN + "Email: " + Task.PatientEmail

After this, I want to play it as audio so that it can be verified by the caller, using a Data expression in the Audio sequence: Task.PatientEmail, using Text to speech.

The Text To Speech sequences before and after the data sequence play correctly, with nothing in the middle.

Take II: The data action, when tested, displays the results in JSON, but the results of the Simple schema are all blank. Where would the discrepancy be, do you know?

JSON: {
"cyclerSN": "35813",
"patientStreet": "350 Merrimack Street",
"patientEmail": "petunia@mygardens.net",
"patientState": "California",
"patientCity": "Lawrence",
"patientPostalCode": "01843",
"patientLastName": "Bush"
}

With the clarity of the morning, I realized that the Schema names != attribute names of the response, i.e. Schema variable 'CyclerSN' is not the same as 'cyclerSN'. Obvious ... now.
