GraphCMS server error: 400 Bad Request

Hi @arroyo - I am testing your program again. Unfortunately, it stops with an error and I cannot debug it.

2021/06/08 11:29:06 GraphCMS server error: 400 Bad Request

How do I debug the tool? Any help is highly appreciated.

Best regards, Max

Hi Max,

Try the backup feature and see if it works...cmsutil backup

looking at your output it seems as though the articles downloaded but it died with the PushNotification download. One common failure is when the schema has an irregular plural name. If the schema plural is PushNotifications then it should work. Plural naming special cases like Person/People would need to be called out in the config.

the tool doesn't have a debug mode...but I can add one. When it does die it's usually from a bad graphql query. Since GraphCMS is an evolving system new schema options may throw off the schema builder. I think a debug mode could help me maintain the exceptions.

Let me add a debug mode and then you can paste any finding here...assuming it's a query issue.

I pushed up a new version. Let me know if the debug data helps...also if it ends up being a cmsutil bug let me know.

Hi @arroyo - thanks a lot.

1. No query variables are printed to debug, e.g.

   {
   "nodetype": "PushNotificationGroup"
   }

2. Results look good. And suddenly it ends. I guess the error is thrown before the failing query is printed. Could that be the case?

The end of a cmsutil-graphcms --debug backup looks like so:

2021/06/14 17:02:39 GraphCMS server error: 400 Bad Request

[arroyo]

Sorry for the radio silence. If you were to copy this query and run it in the graphcms api playground, do you get any specific errors?

BTW I renamed cmsutil to grutil. Hopefully that will clear up any name conflicts.

[xbra]

The GraphCMS docs show, that 400 Bad Request is “typically due to invalid query arguments”. So, printing query arguments in debug mode would be great. Can you please add this?

The last query should be this one:

query GetNodeByTypeVerbose($nodetype: String!) {
  __type(name: $nodetype) {
    name
    kind
    fields {
      name
      description
      args {
        name
        description
        defaultValue
      }
      type {
        name
        kind
        description
        fields {
          name
          description
          args {
            name
            description
            defaultValue
          }
          type {
            fields {
              name
              description
              args {
                name
                description
              }
            }
          }
        }
        possibleTypes {
          name
          description
        }
        ofType {
          name
          description
        }
        interfaces {
          name
          description
          __typename
        }
      }
    }
  }
}

With the following query arguments

{
  "nodetype": "PushNotificationGroup"
}

And the result in the play ground looks pretty okay.
