UDG: Cannot access fields of an input

Product Bug Reports
,
1

After updating to 3.2.0, I’m no longer able to access specific fields of an input using a UDG. I’ve added customer as an input argument in my data model

input customer {
  uuid: ID
  first_name: String!
  last_name: String!
  postal_code: String!
}

and in the data source body I have the below

{
  "first_name": "{{.arguments.customer.first_name}}",
  "last_name": "{{.arguments.customer.last_name}}",
  "postal_code": "{{.arguments.customer.postal_code}}",
  "token": "{{.arguments.customer.uuid}}"
}

yet when I run the query and check the log browser, it evaluates to the below

{
  "first_name": "{"uuid":"123","first_name":"john","last_name":"smith","postal_code":"12345"}",
  "last_name": "{"uuid":"123","first_name":"john","last_name":"smith","postal_code":"12345"}",
  "postal_code": "{"uuid":"123","first_name":"john","last_name":"smith","postal_code":"12345"}",
  "token": "{"uuid":"123","first_name":"john","last_name":"smith","postal_code":"12345"}"
}

Hi @Fahad_Ahmed

You may need to check if your API definition is valid in 3.2.0 as it introduced some breaking changes.

For example graphql.type_field_configurations is no longer used and graphql.engine.data_sources is now the replacement for GraphQL APIs.

Kindly follow our migration guide for more information. If you have further issues then please reply on the thread

@Olu I followed the migration guide to get to this point. My API is valid in 3.2.0. I am creating a new API through the dashboard and it does not have graphql.type_field_configurations

Hi @Fahad_Ahmed

Thanks for bringing this our attention. I can observe the same thing after importing the API definition.

I will check with team and find out if this is possible.

Hi @Fahad_Ahmed

I checked a previous version (3.1.0 to be exact) and found it was working as expected. So I have filed a bug request with the engineering team.

I don’t think there is a workaround at the moment and we do apologize for the inconvenience. I have set a high priority on the bug request and will let you know when I get an update from the engineering team.

Hi @Fahad_Ahmed
I also encountered this issue and the only way I found to overcome this right now is to send the whole input as the body instead of mapping its fields to JSON payload. Like so {{ .arguments.input }} or {{ .arguments.customer }} in your case. If you are using a dashboard to configure the request body it may complain that something is wrong with the request body but it actually works.

Hey @Fahad_Ahmed!
I’m from the UDG team, this issue was brought to my attention today.
We’ll look into this and come back with more info.
