## When Resync Outcomes to LMS Manually I'm getting an error
After using  I'm getting an error
The error can be caused by the following scenarios:
### **1. Multiple attempts are set in the LMS**
When using quizzes with multiple attempts, you should limit the number of attempts as part of the quiz question creation process.
#### How to Resolve the Issue?
For Example, In the LMS (e.g. Canvas) assignment, it should be set to "Unlimited." Learners will not be able to redo the assignment or retake the quiz an unlimited number of times because Annoto is managing the retries, and the LMS (e.g. Canvas) settings do not affect this activity.
The reason for setting it to unlimited is that when we resync the grades, The LMS (e.g. Canvas) counts it as a retry. If learners exceed the allowed retries, Annoto won't be able to resync the grades, which is why you are receiving an error message. Alternatively, you can increase the number of retries allowed.
### 2. Using the same video for assignments and other activities
When creating In-Video Quizzes for a video source or entry, make sure that this video is not used elsewhere in the course. Using the same video in different contexts can lead to students answering quizzes outside of the intended assignment context, such as on a simple page that is not connected to or defined as an assignment. Consequently, their results may not sync properly. This can create conflicts when using In-Video Quizzes and trying to resync the results with the gradebook.
#### How to Resolve the Issue?
Please ask the students who haven't had their grades synced to the gradebook to access the video through the Assignment activity. By doing this, their grades should sync back into the Gradebook. If the grades don’t sync immediately, you can click the resync button to force the update.
### 3. Assignment Due Date Has Passed
Make sure the Assignment Due Date has not passed.
As when clicking on the "Resync outcomes to LMS", Annoto will sync the missing outcomes using the **current date and time**, rather than the original submitted date and time.
#### How to Resolve the Issue?
Extend the deadline for the assignment
Then resync the outcomes to the LMS, and everything will be updated!
## Why do I get a grade passback warning?
If you are getting a warning such as:
This is probably because the activity is in LMS context (type of activity) that does not support grading, such as Canvas LMS Page.
