I had to do some updates to an that are runnning on SharePoint online today. I had to change the schema of one of the lists in the application, the only edits I did was adding a few more options to a choice dialog and editing a displayname. After I pushed the update to the app directory and updateed the application on the site I got a problem.
When accessing the URL of the list I get the following error: "Sorry there were a problem with <App Name>. For suppoert contact the developer. Invalid file name. The file name you specified could not be used. It may be the name of an exsisting
file or directory, or you may not have permission to access the file." When accessing the app on the api I get a reasonable response from the base "<appweburl>/_api/Web/Lists/GetByTitle('ListName'). However if I append Items behind it I get
this error:
{"error": {"code": "-2130575312, Microsoft.SharePoint.SPException","message": {"lang": "en-US","value": "Invalid file name.\n\nThe file name you specified could not be used. It may be the name of an existing file or directory, or you may not have permission to access the file."
}
}
}Another strange thing is the fact that I can see the ItemCount calling the root url of the API. I get 71 Items, and that is correct. Are there any way to repair this list, or beeing able to recover the list data? If anyone are intrested in more information to be able to answer this question, please do not hessitate to request such information
