Error "Command: '522' Error: 'NULL pointer access'."

Issue:

When launching Face SDK, an error occurs: Command: '522' Error: 'NULL pointer access'.

Solution:

Such an error may occur if you have set the value 0 for the recording Process parameter. Or the parameter is not set, and the value 0 is set by default.
To avoid the error, the video should be sent in the liveness package, not as a separate request. Therefore, we recommend setting the value 1 or ignoring this warning.
