If you have imported or copied content from a prior course, in some cases the “date” fields for the Turnitin assignments still display the prior semester’s due dates/availability dates. If that occurs, you may receive the following error after attempting to input your current semester assignment due dates.
[Sorry, we could not process your request. Turnitin assignment could not be created. date_post – post date must be after start date]
To resolve this issue:
- First – click the EDIT button for the Canvas assignment and modify the Assignment Date settings so they are blank. Click Save. You should see the Turnitin assignment window appear below your assignment details.
- Next – click the Turnitin assignment settings gear to edit the Turnitin settings. Clear the date entry from the Start date so it is blank; if applicable, you can also edit the date to your current Assignment start date. Also, change the due date to your current Assignment due date. Click Save/Submit.
- Last – click the EDIT button for the Canvas assignment and modify the Assignment Date settings to include your current Assignment due date and if applicable, start/end dates. Save your assignment changes.
