I'm keen to utilise the new integration with Contentful I wasn't clear on how to follow this part of the documentation so some more clarity/screenshots there might put me on the right course please @strong-mouse-55694 > Add or update your content model Create a new content model or update an existing one to include the GrowthBook Experiment content type. This content type will allow you to create and manage experiments directly within Contentful. Thanks

Hi Joe. That doc clearly has some formatting issues. Thanks for pointing that out. I think it could also be clearer pointing out that Growthbook Experiment content type should be included on a pages via a reference field. So you need to go to your content models and make sure they have a reference field or a reference many field in the place where you want to run an experiment.

Thanks James I'm getting an error when I try to set up the experiment - which looks like a 400 error from the cdn.growthbook.io api. I checked my config and it looks ok How should I debug that?

Sorry about that. That's not a very helpful error message is it. I'll look into it and get back to you ASAP.

Thanks James. I tried the other other API endpoint and I'm having the same problem. Within this content type, I have picked an existing field ('product') which is a reference, and added

Growthbook experiment

to the valid entry types. I get the error as soon as I go to make a new item using this content type. Even before I've selected to build a growthbook experiment.

Hi Joe, sorry that you have a new issue. It's a bit hard to know exactly what is going on here. My guess is the entry is in some error state that the plugin hasn't been coded for. Now that the API server URL is correct, I'd imagine that perhaps if you created a new Growthbook Experiment from scratch it might work. Can you see if you can reproduce this problem on a brand new experiment?

I don't even get as far as creating an experiment. The error happens as soon as I go to make a new product.

If you go back to the main "content" list from the top menu. Then click "Add Entry" and click "Growthbook Experiment", then make a new experiment name and add two variations, and click Create Experiment, does that work now?

No luck.

Hi Joe. The "Growthbook experiment" sidebar should not be showing on the "Super hero" content type. The installation of the Growthbook plugin only adds it as a sidebar widget on "Growthbook Experiment" content model. Did you add it manually to the sidebar? If so you can remove it.

Sorry James, still no luck 😕

I have added a warning now if the Growthbook Experiment is loaded in the wrong content type: https://github.com/contentful/marketplace-partner-apps/pull/4366

I haven't changed the setup from this

yeah it has the correct url there at the end, but something is inserting stuff before hand. Perhaps there is a site wide proxy setting or such.

ok we are a step forward 🙂 it'd be helpful update this to reflect the full url

it'd be helpful update this to reflect the full url

Yes I have a PR that is half written that does that and some other extra validation on the configuration page.

Thanks James! Appreciate your partnership!

Likewise.

Hey @white-fireman-22476; wondered if you'd managed to make the fix please?

@white-fireman-22476 Hi James, I’m Andrés, I’m an engineer with TodayTix, picking up some of the work that Joe has been doing with you. I have run in the same error Joe run into when trying to publish a

Growthbook Experiment

entry. It renders the following error:

Unrecognized assignment query ID: user_id

I checked the API call that is being done to GB, it is POSTing an entry to the

experiments

endpoint, with the following payload:

{
  "datasourceId": "REDACTED",
  "assignmentQueryId": "user_id",
  "trackingKey": "andres-contenful-test",
  "name": "andres contenful test",
  "variations": [
    {
      "name": "Control",
      "key": "0",
      "id": "4ajdZxDD1jcEuAezXyLDS0"
    },
    {
      "name": "Variation A",
      "key": "1",
      "id": "4zusFvHuVtpYLUkfBKFb6s"
    }
  ],
  "description": "Created from [Contentful](<https://app.contentful.com/spaces/REDACTED/entries/2JcbY9T7Jjkyy1iXJMdYUG>).  \n\n#### Variations  \n**Control**: Gypsy Takeover  \n**Variation A**: WL Musicals Banner hamilton\n        "
}

The endpoint returns a 400 error, with the rendered message.

user_id

does exists in our data source. Would that information help you troubleshoot what might be going wrong with our experiment? Thanks in advance for your help. cc @hundreds-midnight-51493
