• When a user requests leave, first he will get a successful message for submitting the request.
• Then the request will deliver to the manager, for approval or reject the request. If the manager approves or rejects that request then the user will get an approval or rejection email and this will update on the SharePoint list. If it is rejected then it will not go to CEO for approval.
• Otherwise, it will go to CEO for final approval. Then the user gets the final approval for the leave request and also, the item gets updated on the SharePoint list.
• But we faced the issue when the final level approval occurs i.e. CEO level approval. Especially when the CEO rejects the request, an error is coming like below:
