Build failed: typeerror: cannot read property ‘configs’ of null

The reason for the error is that I used version control management tools carelessly in the process of using, resulting in the failure of the project services.json There was a conflict, so I put the services.json If the file is deleted, the project will be re opened with cocos creator, and the file will be re copied from the engine library, that is, there will be no conflict problem, and then there will be no problem in rebuilding.
