: variables map can't be null V16.2

[skumaravelan]

I have upgrade the GraphQL library from 11 to 16.2 and am getting graphql.AssertException: variables map can't be null error
Is there any fix or configuration to load schema without variables.

I experienced a similar (same?) error - not sure of your context. My context was testing with GraphiQL using HTTP GET method. It includes variables as a query parameter that is literally text "null" (excluding quotation marks), not "no-value" null when variables aren't specified. That is invalid and "prints" the same. I handled this in my servlet, treating &variables=null as unspecified (truly null) variables parameter.

GraphQL Java is just the execution engine which doesn't deal with Http or how to load the schema.

I expect you are using a library on top of GraphQL Java which causes this problem.

Previous version there is no null check required and now it failed, I have added null check to move forward.
