Also tried adding DateTime as custom scalar field but it is throwing the same error ``` private RuntimeWiring buildRuntimeWiring() { return RuntimeWiring.newRuntimeWiring() .scalar(ExtendedScalars.DateTime) .build(); } ```

The issue is cause by horizontal scaling of prisma service where 2 service attempts to connect to management api. #2850 https://techblog.commercetools.com/prisma-horizontal-scaling-a-practical-guide-3a05833d4fc3
