Unable to invoke face liveness view

[LiangLuDev]

Describe the bug

Feedback from several users indicates that when attempting to open the facial verification page, a blank page is displayed.
I have not been able to replicate this issue myself, and there are no error logs, so I am unsure how to troubleshoot this error.
I need assistance in troubleshooting.

This issue occurs sporadically;
most users can use the feature normally, but a small number of users are unable to use it.
Attached are videos showing the feature being used normally (by me) and the issue where it cannot be used, along with screenshots of the code.

@LiangLuDev I have not been able to reproduce this issue. It looks like there's been several bug fixes releases from the current version you're using. Are you able to update to the latest released version and see if issue still exists?

Are you able to add additional logging to see if an error code or exception is returned from the component? Are you observing this issue on any specific iOS version or device?

[LiangLuDev]

I have already added logs to the location where results can be obtained, but there is no error information on our analytics platform. From the feedback, it seems that the issue is not related to the iOS version, as the errors occurred on different iOS versions. I will first update the Amplify-related versions and see how it progresses.

I have upgraded the package to the latest version, but git status does not show any changes. How can I confirm that I have upgraded to the latest version?

[phantumcode]

@LiangLuDev Yess, version 1.2.13 is the latest version.

Hi @phantumcode .
I would like to inquire whether there are any restrictions related to facial recognition authentication for user accounts. According to the data I reviewed, our facial recognition feature has been live for approximately two months. However, we have recently received increased feedback about users being unable to invoke the facial recognition page in the past two weeks, despite there being no modifications made or new versions released during this period. I am unsure where to submit a ticket to track and address this issue.

@LiangLuDev Can you clarify what you mean by "restrictions related to facial recognition authentication for user accounts"? Your authentication and user accounts are up to you to setup and maintain. Your backend service to create the session id and get the result are up to you to setup and maintain.

Also, please clarify and be more specific on what you mean "unable to invoke the facial recognition page in the past two weeks". Are the users unable to create a session id? Are the users unable to get the result? Are the users able to get a session id and start a liveness session and unable to complete the liveness check? If so, what is the exception or error message you're seeing or capturing? Do you have example of sessions that are running into this issue? If so can you provide the session ids that the service team can look into? Are this issues occurring on a specific platform (iOS/Android/Web) or specific region?

[LiangLuDev]

Currently, this issue is only occurring on the iOS platform.
Based on all the logs and screen recording analysis available to us, user login sessions are successful.
The redirection to the facial recognition page occurs only after the user successfully creates a session. This can be observed from the code screenshot provided earlier.
I will share the session ID with you tomorrow.

As stated above, I am unable to reproduce this issue myself. This feedback was given to me by a user.

When I call Amplify.configure(), an error occurs, but the facial recognition page can still be invoked normally. Will this have any impact? I noticed that your demo is also written this way.

Unable to configure Amplify PluginError: Could not cast incoming configuration to JSONValue
Recovery suggestion: The specified configuration is either nil, or not convertible to a JSONValue. Review the configuration and ensure it contains the expected values, and does not use any types that aren't convertible to a corresponding JSONValue:nil
