Wechat sometimes jumps out of the WeChat applet and the push fails.

1. The first common reason

Forgot to register in the pages option of the app.json file.

2. The second common reason

Wrong jump path

3. The third reason

If the jump path has been registered in the TabBar option of the app.json file, then the jump method needs to use the wx.switchTab method to jump.

Note: the first two reasons are easy to find, because the console will have corresponding prompts, and the third console will not report an error, so it is difficult to find.
