File Upload Error - JSON String
Last modified on 29 November 2022 11:38 AM

On rare occasions, users may encounter the error 'Invalid JSON string' when trying to upload files. Possible reasons for this include:

  • Internet Explorer. Instead, try uploading the file with one of the recommended browsers for eClass.
  • Uploading a file greater than the course upload limit. This is a course setting with a default of 100 MB. You may need to find an alternative way to upload large files if it exceeds the maximum, i.e. file compression, Google Drive, etc.
  • Filenames containing special characters. Rename these files to exclude them and try again.
