If you get this message, it is likely that there really is an error in the manifest or locale files (for example, in my case it was the trailing comma in the locale files).
Process y to solve the problem:
Try installing the version of the application that you just sent to the chrome store. When you try to install the application, you will probably receive an error message indicating that the manifest file is tracking the problem.
I fixed the problem in the application and downloaded it again. You may get the same error in the developer panel. Two things can be added:
A) If you have already fixed all the errors in the manifest files in order to post the changes, and more importantly, the publication process could take several minutes to become effective. The message will disappear after a while if everything is in order. (This explains why you look at this problem on the Internet, you will find that people say that the message will disappear after a while)
B) If the error event persists after the publication process is completed. You may not have resolved the entire error in the manifest file, return to step 1
