问题
I have an issue when I want to add the Google Mime Types in the developer console to allow my app to open Google Files. In the developer console in the section "Integrate with Drive interface" I set some mime type like 'application/pdf' or 'image/png' no issue and in the drive interface in the open with menu I find my app.
I want to set Mime Types for Google Drive files but when I want to save modification in developper console I get an error "User request is not valid. Please verify your url and retry". This is not the real error because I got it in french. Exact error message : The user request is invalid. Please check your URL and try again.
I tried Mime type we found here : https://developers.google.com/drive/web/mime-types?hl=fr
I also tried Mime Type like : application/vnd.google-apps.kix for gdoc or application/vnd.google-apps.ritz for sheets but no results. I also tested gsheet, gdoc but no result.
If I try application/vnd.google-apps.folder it works.
I tried to add that in the Default Mime Type and Secondary Mime Type field but same result.
I don't know what to do more....

In fact to open a Google document with your app in Google Drive you have to check the importing function (Allow users to open files that can be converted to a format that this app can open.) See ref : https://developers.google.com/drive/web/integrate-open#open_and_convert_google_docs_in_your_app
My understanding is you can't open a google document but just "import in your app" the current version in a specific format. Don't forget to add in the mime type your app can open a mime type the google file can be exported. See google developer page for a compatible mime type.
