Good morning.
On August 26th of this year, I published a version of an app built with React-Native. Everything went smoothly, and the internal test reports sent by the store did not show any issues. However, on September 27th, when launching a new version, Google Play Console reported undefined is not a function error for the following devices below.
Since I do not have these devices physically, I downloaded emulators for the specified Android versions and ran the app natively, using the Android folder. However, I was unable to replicate the issue.
I searched through every part of the code for something that could be causing the problem, but I couldn’t find anything wrong.
I then began to suspect that the issue might not lie in my logic. So, I decided to remove all logic entirely. The only change made was updating the project version; everything else was exactly the same as the stable version from August 26th, including the files package-lock.json, package.json, and yarn.lock.
To publish the app, I executed the command cd android && ./gradlew clean to clean all the build files in the Android folder. Then, I deleted the entire node_modules folder and regenerated it to ensure there were no corrupted packages. After that, I ran the command ./gradlew bundleRelease to generate the package in AppBundle format for release.
And guess what: the stable version, which had not reported any problems when published on August 26th, now presented the same issue: undefined is not a function.
I updated the packages using yarn upgrade, but the error still persisted.
I’ve read every type of forum about this issue, but most of them stated it was a code error. Unfortunately, I no longer know how to proceed. How is it possible for a version with the same code to start showing issues out of nowhere, especially when no errors were detected in the pre-launch report the first time it was published?
Below is the error reported by the Play Console.
Exception com.facebook.react.common.JavascriptException: TypeError: undefined is not a function
