There was a codename collision when transforming content type and content type snippet codename to a GraphQL type name. Your GraphQL type 'PageNews' is generated from content type {"Name":"Page - News","Codename":"page___news","Id":"9a075af6-3a03-4268-bf9a-f7e9994e6198"}, content type snippet {"Name":"Page News","Codename":"page_news","Id":"45edbc35-3367-4c67-9c8e-6e7cbcd38e01"}. To fix the codename collision, use such codenames for your content type and content type snippet that remain unique even after removing the underscore characters.
