Cannot Convert undefined or null to value when querying and field is null (but schema is valid)

[nalejandroveron]

Intended outcome:
I was running a query, expecting it to get the data via props.

Actual outcome:
The data never came, instead i got an error as you can see in the screenshot:

File: node_modules/graphql-anywhere/lib/graphql.js Line: 123

File: node_modules/graphql-anywhere/lib/graphql.js Line: 123

How to reproduce the issue:
Run a query with an non-required field and with null as value, at least that's the apparent reason

As you might see, is allowed to be null:

The same query was working before (because we had an production version that's still working), but i wasn't able to track which version made this break, please, let me know if we need more info or something else

Version

• apollo-client@2.3.0
• graphql@0.13.2
• graphql-anywhere@4.1.9
• graphql-tag@2.9.2
• react-apollo@2.1.3
• apollo-cache-inmemory@1.2.0
• apollo-fetch@0.7.0
• apollo-link@1.2.2
• apollo-link-http@1.5.4

EDIT:
After doing a lot of checking, graphql-anywhere was the dependency that's breaking my code, if i use an npm-shrinkwrap.json to pin the version to 4.1.8 everything works correctly again (had to do this because apollo-cache-inmemory will install 4.1.9 instead). So this issue came from the release 4.1.9 as far as i can see

I believe the issue was introduced in commit 6abcd72#diff-59e1428b6685d109077bc48ba0452c38R233

The merge function no longer checks if src is type object.

Try graphql-anywhere@4.1.10?

Yup, it's working again, thanks!
