422 error when submit TestFlight Beta Review

When I submit the app to TestFlight beta review I get the error show on UI. (I filled all filed info in Beta Infomation)

There was an error processing your request. Please try again later

I was inspected Safari to see the detailed error and I got the below error.

Failed to load resource: the server responded with a status of 422 ()

and the detailed javascript error

componentStack: undefined

errorCode: undefined

message: "API Response Error: TF_BETA_APP_REVIEW_RESPONSE"

stackTrace: "status code: 422 --- api correlation key: NZEKCTWMNANXDZVTRD3V4GNE3U"

Anyone can tell me the problem and how to fix it. Many Thanks.
