JSON parse error: Cannot construct instance of `java.util.LinkedHashMap` about graphql-spqr-spring-boot-starter HOT 4 CLOSED

Not sure where LinkedHashMap is coming from?
The mentioned field io.leangen.graphql.spqr.spring.web.dto.GraphQLRequest#variables is of type Map<String, Object>, not LinkedHashMap.

Do you have some strange Jackson configuration? Are you on version 0.0.3?

from graphql-spqr-spring-boot-starter.

I get a very similar error, trying to use

objectMapper.convertValue(map, MyClass.class);

Where MyClass has an Map<String,String> field, which I am trying to set to an empty Map via "{}"

java.lang.IllegalArgumentException: Cannot construct instance of `java.util.LinkedHashMap`

@nngo Wait... I don't see any GraphQL SPQR in your example. How does it relate? Can you post an example that reproduces the issue?

from graphql-spqr-spring-boot-starter.

@nngo I think I found what was causing issue. It is fixed in the next release of SPQR (0.10.0), so the next release of the Starter (0.0.5) should have the fix as well.
If you keep having problems, feel free to reopen.
