As far as I understand there is a check that something have to be returned https://github.com/Codeception/base/blob/3.1/src/Codeception/Lib/Connector/Yii2.php#L363, but in case of DELETE method there is no any output, so this condition should not be applied.

Please make pull request to https://github.com/Codeception/module-yii2/ to fix it.

[SamMousa]

No, the check only fails if response content is non empty and the data we captured is. So in your case, you are probably setting the response content in your code, which makes no sense for a delete method handler.
