8base deploy/commit. Something went wrong during build graphql schema

I have a question regarding creating a mutation resolver. When trying to deploy it I get the message from the title.

I found out that the problem is the type [Check], which is an array of a table defined in 8base.

Am I missing sth? Is this the way of defining an input for a mutation resolver?

Hey there - can you jump into the API Explorer and look at the Documentation of your API? I just want to confirm that you’re using the right Type name (for example, if its a mutation you may want to use CheckCreateInput or something along those lines).
