Describe the Issue

When using a collection variable with type number (e.g. 42) in a gRPC unary input with type uint32 (e.g. {{myVar}}, postman declares "Incorrect Type. Expected one of integer, null." and prevents the method from being invoked.

The IDE always had the yellow squiggles but was working. The blocked invokation behaviour started within the past few weeks.

Steps To Reproduce

1. pm.collectionVariables.set("myVar", 42)
2. Use a unary gRPC request with message input such as { "id": {{myVar}} }
