MybatisPlusException: can not use this method for “getEntity“

Use mybatisPlus to automatically conditionally manipulate data;

The incoming execution query conditions are as follows:

Wrapper<DigitalNewspaper> wrapper = this.lambdaQuery().eq(DigitalNewspaper::getNewspaperType, newspaperType).eq(DigitalNewspaper::getReleaseDate, releaseDate);

List<DigitalNewspaper> digitalNewspapers = ((LambdaQueryChainWrapper<DigitalNewspaper>) wrapper).list();

The above query list can be operated normally;

When executing the delete method, the following error is prompted;

Conditions continue to use those from the list above;

Wrapper<DigitalNewspaper> wrapper = this.lambdaQuery().eq(DigitalNewspaper::getNewspaperType, newspaperType).eq(DigitalNewspaper::getReleaseDate, releaseDate);

this.getBaseMapper().delete(wrapper）;

The error message is as follows:

MybatisPlusException: can not use this method for "getEntity"

 

I later found this error online; it was said to be caused by an official mybatisPlus bug; it can be solved by modifying it as follows:

LambdaQueryWrapper<DigitalNewspaper> lq = Wrappers.lambdaQuery();

this.getBaseMapper().delete(lq.eq(DigitalNewspaper::getNewspaperType, newspaperType).eq(DigitalNewspaper::getReleaseDate, releaseDate));
