Hello everyone, when I use grid to display data, the data is displayed normally when I use one grouping condition, but when I use multiple grouping conditions, an error will be reported. The database I use is mysql, and the error is when I call the todatasourceresult method

This is one grouping condition

This is two grouping condition

Here is my code and error information
