Actions stopped working

### Version Information
2.14.0

All of my Hasura actions stopped working after i updated to latest version v2.14.0, i constantly keep getting the same error

The Error:
`{
"errors": [
{
"extensions": {
"code": "unexpected",
"path": "$"
},
"message": "Response Transformation Failed"
}
]
}`

The Action types
`type Query {
auth(
username: String!
password: String!
): AuthResponse
}`
`type AuthResponse {
session_token: String
}
`
My Rest Endpoint Code
`export const auth = async (request: Request, response: Response, next) => {
response.status(200).json({ session_token: 'sometoken' })
}`

Start by reproducing the failure in Hasura Actions using the reported v2.14.0 version, the auth action schema, and the shown REST endpoint response. Trace the action response transformation path and compare its behavior with the reported error; done means the action returns the declared AuthResponse without a Response Transformation Failed error.
