Is there a way to avoid graphql error when yaml's array element is empty

[github0013]

Summary

I understand yaml files need proper contents according to graphql queries in codes, but in my case, yaml contents are dynamic. They are sometimes no data (I update yaml files before a build).

If an array in yaml is empty, graphql queries using the yaml will fire an error. This error is critical, and it stops the process when to build.
** I need to show the page with the empty data. (I can't skip the page)

This is how I avoid the build error.

Here are my questions

1. Is there a way to avoid this graphql error when you have such an empty array?
2. Can we implement yaml data type definition in gatsby? so that we can simply have an empty array data without being worried about filtering out the dummy type definition data (see https://github.com/github0013/empty_yaml_load) ?

As you can see in the issue #2392 (comment) (and the linked issue) that's currently the only way to circumvent this error.
