I need some help troubleshooting this error which I see in the Network tab of my browser console when I try to Continue from the first checkout page when logged into SuiteCommerce as a customer:

{
  "errorStatusCode": "400",
  "errorCode": "ERR_WS_FIELD_NOT_SUPPORTED",
  "errorMessage": "You have attempted an unsupported action."
}

The errorMessage appears in a little pink error notification in one place on the checkout page, or three places if it's one-page checkout. It doesn't really tell me much, and I don't see any Server Script Logs about it when I search them. Whatever is throwing this error seems to also be preventing the user from advancing to the next checkout step.

Is it getting thrown by the LiveOrder.Service? I would think it could be a client script deployed over the Sales Order that could be the culprit

Network tab shows the error is the response from /scs/extensions/SuiteCommerce/CustomFields/1.1.4/services/Checkout.Service.ss

oh ok that’s used by the Commerce extension from netsuite for custom fields, so it might be when trying to update a field that the client script is executed. You can check if you have ” SCRIPTABLE CART AND CHECKOUT” checked in your website record and if you are in a staging or sandbox you can see if you uncheck that if it works (after opening it in incognito window)

Here's the payload of the submit request:

      "module": "Shipping Method",
      "type": "Header",
      "label": "Pick-up instructions (will be included on your order confirmation):",
      "placeholder": "",
      "mandatory": false,
      "maxfieldlength": null
    },
    {
      "internalid": "custbody_checkout_custpickup_instr",
      "position": "After",
      "module": "Shipping Method",
      "type": "Text Area",
      "label": "",
      "placeholder": "",

    }
  ],
  "custbody_checkout_specshipinstr": "",
  "custbody_checkout_deliveryhoursfrom": "",
  "custbody_checkout_deliveryhoursto": "",
  "custbody_checkout_liftgaterequired": false,
  "custbody_checkout_custpickup_instr": ""
}

Now, there is at least one more field on the form that is not appearing in the submit request, and that field is custbody_checkout_hasreadtcs

I’m thinking of scripts because of the FILE NOT SUPPORTED error, if it was a field it shouldn’t have a file involved

I do have the online forms set to custom forms that have clientside scripts attached, but the clientside scripts don't do anything except set a test variable to a string value, and that variable isn't used anywhere. I came in after these were added so I don't know why we have them, but I don't think it's doing anything in the form clientscript, and Scriptable checkbox is unticked.

does custbody_checkout_hasreadtcs have the checkbox “Web Store” checked?

I read somewhere that certain field types are not supported in SuiteCommerce, but these are fields I was using last time I built this web store, and was not getting that error at this time (I have built this web store a few times but each time before in Sandbox but never created it in Production, and had to refresh the sandbox a few times, and there's no good Web Store backup and restore method in place that I know of)

Yes, there should be custom body fields associated for each of those fields in the custom field extension

Well that might be why it's not working 🙂 I'll go make sure they have custbody fields existing in the custom Transaction Body Fields.

the id should match exactly so when creating the body field make sure to create it without the custbody part since that is added by netsuite

That fixed it! I'll need to add that to my list of things that need to be re-created if we refresh the sandbox before deploying to production again.

awesome! i’m glad it worked
