#Overview

After a Mini Program has been developed and is ready to be published through the WeChat Mini Program channel, code submission may fail for several common reasons. This document lists the typical errors and gives recommended fixes. For issues that require code changes, you can adapt the provided prompt and send it to MeDo so it can modify the project.

#Error 1: Authorization Error, Try Reauthorizing the Mini Program

#Case 1: The third-party development platform is not authorized or has insufficient authorization

Fix:

Scan the code and go to WeChat Open Platform > Management > Version Management > View Authorized Third-Party Platforms > Third-Party Settings > Third-Party Platform Authorization Management. Reauthorize the platform on the WeChat side. Do not authorize multiple platforms at the same time.

#Case 2: A required plugin interface has not been enabled

Fix:

Scan the code and go to WeChat Open Platform > Management > Development Management > Interface Settings. Enable the interface named in the error message. For example, if the error says error [getFuzzyLocation] is not authorized, enable the wx.getFuzzyLocation interface.

#Error 2: Plugin Permission Configuration Error
