Spock Error while handling ["v1","graphql"]: InvalidUrlException "" "Invalid URL"

I have Hasura Graphql v2.35 running in my server where suddenly the one of the insert mutation started throwing error internal server error 500

Very unusual of hasura to throw error which is not descriptive.

On inspecting the Hasura logs all i can see the

Spock Error while handling ["v1","graphql"]: InvalidUrlException "" "Invalid URL"

What might be causing the Invalid URL where all other mutation and queries are working fine? and no new change except permission changes to this entity.
