This error occurs when the appInfo property is being accessed on an undefined object.
To fix this error, make sure that the object containing the appInfo property is defined and has a value before attempting to access its properties. You can also try checking for null or undefined values before accessing object properties using conditional statements or optional chaining.
If you are using a third-party library or plugin, make sure that it is installed correctly and that all required dependencies are included. Also, check the documentation for any specific configuration or initialization steps that may be required.

uniapp Uncaught (in promise) TypeError: Cannot read property 'dispatch' of undefined
This error occurs when you are trying to use the dispatch method on an undefined object in a Uniapp application.
To resolve this error, you need to make sure that you have defined the object that you are trying to dispatch. Check that the object exists and is initialized before you try to use it.
You may also want to check that you are using the correct syntax for the dispatch method. Make sure that you are passing in the correct arguments and that you are calling the method on the correct object.
If you are still having trouble, you can try debugging your code by adding console.log statements to see where the error is occurring and what values are being passed in to the dispatch method. This can help you identify the root cause of the problem and find a solution.
Uncaught (in promise) TypeError: Cannot read properties of undefined (readin
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'randomExtend')错误通常发生在Promise中尝试读取未定义变量的属性时。这可能是由于异步操作返回了一个未定义的值,导致无法访问该值的属性。解决此问题的一种方法是在读取属性之前添加null或undefined的检查。
类似的错误Uncaught (in promise) TypeError: Cannot read property 'removeChild' of null是因为试图在null对象上调用方法。这通常表示在执行操作之前,应检查对象是否存在。
另一个错误Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'code')可能是因为在自定义拦截器中忘记将promise对象返回。确保在自定义拦截器中正确地返回promise对象,以便将其链接到其他操作。
总结回答:
