How to configure GraphQLBundle to pass an array of objects to input args?

Question

symfony

I have these configs:

Mutation:
    type: object
    config:
        fields:
            CreateUserReportConfiguration:
                type: CreateUserReportConfigurationPayload!
                resolve: "@=mutation('create_user_report_configuration', [args['input']])"
                args:
                    input:
                        type: CreateUserReportConfigurationInput!

CreateUserReportConfigurationPayload:
    type: object
    config:
        fields:
            id:
                type: "Int"
            user_id:
                type: "Int"
            fields:
                type: "[ColumnReport]"
CreateUserReportConfigurationInput:
    type: input-object
    config:
        fields:
            user_id:
                type: "Int!"
            fields:
                type: "[ColumnReport]!"

in CreateUserReportConfigurationInput.config.fields.fields.type as a parameter, you can see how I want to pass an array of objects, described in the corresponding file:

ColumnReport:
    type: object
    config:
        fields:
            column_name:
                type: "String"
            table_name:
                type: "String"

But at the moment, the bundle returns a 500 error with the text
The type of CreateUserReportConfigurationInput.fieldList must be Input Type but got: [ColumnReport]!. That is, it tells me that I cannot send an array of objects to the server via graphql, which, in my opinion, is some kind of nonsense. How to deal with this problem? I need to send an array of ColumnReport objects in this fields field.
