Syntax Error: Expected Name, found }

[daquintero]

Hello jexp, first thanks for the project, it looks very useful.

I'm having a problem when running the grapqhl load that maybe you would know what it would mean.

Using endpoint local: {"url":"http://localhost:4000"}
Using mutation "post": "".
Done parsing CSV-file /Users/Me/Desktop/devtest/hackernews-node/reviews.txt rows: 3
 meta: {"delimiter":"\t","linebreak":"\n","aborted":false,"truncated":false,"cursor":571,"fields":["episode","commentary","stars"]}
Using mapping: {"description":"commentary","url":"stars"}
Sending query:
mutation { 

}...

Syntax Error: Expected Name, found }: {"response":{"errors":[{"message":"Syntax Error: Expected Name, found }","locations":[{"line":3,"column":1}]}],"status":400},"request":{"query":"mutation { \n\n}","variables":{}}}

I'm running the database API with prisma, and I have uploaded my whole minimum viable test project to get this functionality working in this repository: https://github.com/daquintero/testGraphqlCLILoad/tree/master

I'm not sure if this is enough information for the question, but please tell me if you need anything else. I appreciate very much the help!

I've found https://github.com/prisma/prisma/issues/1981 but I'm not sure its relationship given that in the graphql playground localhost:4000 the mutation works correctly, but through the graphql-cli-load I get this error.

Solved it, the mappings inside the const column=(rMapping[key]||key).toString(); were not giving me the correct column headers for the values generation that is used in the mappings, so I changed it to const column = mapping[key].toString() which gave me the correct mappings when using this output:

$  graphql load --csv reviews.txt --mutation corruptionIn --mapping '{ "url" : "commentary", "description" : "stars", "postedBy": "episode"}'

I will send a pull request for this correction and if you want we can use my repository as the minimum viable graphql-cli-load example code that currently does not exist in a "plug in -and - run" sort of thing.

[daquintero]

I also removed the original example repository since I have now copied the working version of the minimum example code as a separate branch of my own fork here

[jexp]

Sounds great, thanks so much ! sorry was away over the weekend so I didn't see your initial issue immediately.

[jexp]

Your original issue looked like a missing/incorrect mutation name?

[daquintero]

Hey jexp, thanks for the reply. Apologies for the unclean code, I will be more careful with presenting it better next time. Would I suggest continuing to discuss this issue here before continuing at the pull request? I will also make it better as soon as I can.

So I was trying to run this command:

graphql load --csv reviews.txt --mutation corruptionIn --mapping '{ "url" : "commentary", "description" : "stars"}'

And I had defined this resolver in src/resolvers/Mutations.js from my most minimum example:

async function corruptionIn(parent, args, context, info) {
	const userId = getUserId(context)
	console.log("All arguments are: " + JSON.stringify(args)) 
  return context.db.mutation.createLinkC(
    {
      data: {
        url: args.url,
        description: args.description,
        postedBy: args.postedBy,
      },
    },
  )
}

Also running this mutation in the graphql playground, it worked:

mutation {
  corruptionIn(
    url: "sasasdasdd"
    description: "asddatabase into a GraphQL API"
    postedBy: "heey"
  ) {
    description
    id
  }
}

Would you think it still might be related to the mutation name in the grapqhl load command or in some other part of my command? I tried to replicate the example described in the README.md in your project page. Would you see any part where I implemented it incorrectly? The names of the mutations may be very strange as I was chucking the mutations from another project in, which may have seemed confusing.
