We are trying to create a custom module that integrates with ShuftiPro which is used for face identity verification. After successful compilation of the module, it is uploaded to the mobile channel. Now, when we are rebuilding the app, the build is failing with the logs below.

We have done all the three steps mentioned in "Adding third-party dependencies" community document.
