Fix for the issue Files keep loading when previewing all files in OneDrive as mentioned in #1994

Issue

While using FilePicker control, When switching to the OneDrive tab in the FilePicker, it shows a loading spinner indefinitely and never displays the files. All other tabs in the FilePicker — such as Recent, Site, and Upload — work as expected and load properly.

Solution

(Root cause analysis was already done by the issue reporter)
The title of the documents library will vary if the system language is different other than English. For instance, The document library Title in English is as Documents where-in, in swedish it is Dokument.

By checking the default language as below,

  public isCurrentLanguageDefault(): boolean {
    return this.context.pageContext.cultureInfo.currentUICultureName === 'en-US';
  }

and having a conditional check as below,

      const isDefaultLang = this.isCurrentLanguageDefault();
      const myDocumentsLibrary = oneDriveLibsData.value[0];
      this.oneDrivePersonalLibraryTitle = isDefaultLang ? myDocumentsLibrary.Title : myDocumentsLibrary.EntityTypeName;
      this.oneDriveRootFolderRelativeUrl = `${myDocumentsLibrary.ParentWebUrl}/${isDefaultLang ? myDocumentsLibrary.Title : myDocumentsLibrary.EntityTypeName}`;
      this.oneDriveRootFolderAbsoluteUrl = `${this.oneDrivePersonalUrl}${isDefaultLang ? myDocumentsLibrary.Title : myDocumentsLibrary.EntityTypeName}`;

Resolves the issue.

Thanks,
Nish
