Hi,

I'm getting a 400 - Bad Request with response body

{"errorMessage":"There was a problem processing your request. Please try again.","httpStatus":"400","numberOfAttempts":1}

'before creating the user' as part of the built in user flow. The Api Connector is pointing to an Azure Function.

I'm seeing the 400 within App Insights, but it's not actually hitting the function method, i.e. this error message appears to be generated by Azure.

Calling the Azure Function manually via Postman works fine.

Any ideas on how to solve this problem?

Thank you
