WeChat applet wxs calls callMethod to report rendering layer error Call method on a non-custom-component node is invalid......

The console prints the error content as follows:

[渲染层错误] Call method on a non-custom-component node is invalid. Call on the owner component or page instead. To avoid this error hint, try not to call method on `event.instance` , but on `ownerInstance` instead.

After testing, it can be called normally, but it is unbearable to report errors.

Originally, I wanted to obtain a component instance to change its style, and then directly called the `callMethod` method of the component instance, but the console reported an error. The code example is as follows:

module.exports = {
    touchstart: function(event, instance) {
        var test = instance.selectComponent('.test');
        // ...
        test.callMethod('testCallMethod', {});
    }
}

I have never understood the reason. After looking at the official documentation, I noticed that the documentation stated that it is "current component/instance" to understand what is wrong.

 The correct code example is as follows:

module.exports = {
    touchstart: function(event, instance) {
        // ...
        instance.callMethod('testCallMethod', {});
    }
}
