Error Message: “Exception Thrown: Attempt to convert non-date value”


This is ONE of the types of “Exception thrown” errors, but it references “unable to convert date..” and then some other language. This means the time/date format on the machine is not one MSP supports.

 In Windows:

  1. Go to the Date and Time Settings on your computer and look for "Change date and time formats"
  2. Make sure the Short Date format is either mm/dd/yyyy or dd/mm/yyyy (the "/" as a date divider is key, for example if using mm-dd-yyyy it could throw the error)


In Mac OS:

  1. Click on the date/time in the top right section of the menu bar. 
  2. From the menu, select Date & Time Preferences…
  3. Then click on Open Language & Region…
  4. And select the Advanced… button.
  5. In the window that appears, we want to select the Date section.
  6. Then, using our mouse to drag the different date elements around, we want to make sure our short date is in the MM/DD/YY or MM/DD/YYYY format.
  7. Then click OK to save and apply.
