Thank you @xuzhang3 for making this fix. In addition, Is it possible to add a test case to cover this business flow in this PR for I'm impressed that this bug was not caught was because there was no test coverage, or, is there already a test case covering this flow while that test case has been failed due to this crash bug?

Hey @xuzhang3, this fixes the current crash but we should take it one step further to prevent potential future panics

[mbfrahry]

We should check that stage is a map[string]interface{} before casting to it to prevent another potential crash

Type assertions added
