Expense ID available in the Expenses table but not found using REST API, getting 404 error

Summary:

We have a couple of Corporate Card Expense lines, that are available in the exm_expenses table. Unfortunately these lines are linked to Expense Template IDs that no longer exist in the system.

We tried to correct these lines using REST API, but we are not able to find these expense IDs in REST API. We are getting the 404 error as below:

HTTP/1.1 404 Not Found

Any suggestions as to what we can do to find the Expense ID so that we can we can correct the business unit and template mapping?
