Decimal / Numeric Postgres fields return null value in operations

[a11dev]

Description

When attempting to access the value of a numeric (decimal) field with Prisma Data store / Postgres, the field always returns null in all operation types. If the returned field is the table pk the output is an array of null.

Same as [Decimal / Numeric Postgres fields return null value in operations] #1166).

Reproduction

Create a postgres table:

CREATE TABLE "TasksRemap" (
    key Numeric PRIMARY KEY,
    field1 VARCHAR(255),
    field2 DATE,
    field3 NUMERIC
);

insert some value

INSERT INTO TasksRemap (field1, field2, field3) VALUES
(1,'String1', '2024-04-01', 100),
(2,'String2', '2024-04-02', 200),
(3,'String3', '2024-04-03', 300),
(4,'String4', '2024-04-04', 400),
(5,'String5', '2024-04-05', 500);

from the wundergraph nextjs example:

defining the datasource into .wundergraph\wundergraph.config.ts
mine:

const dbpg = introspect.postgresql({
	apiNamespace: 'dbpg',
	databaseURL: 'postgresql://user:password@address:5432/dbname?schema=public',
	introspection: {
		disableCache: true,
	  },
	  replaceCustomScalarTypeFields: [
		
		{
			entityName: 'TasksRemap',
			fieldName: 'field3',
			responseTypeReplacement: 'Float', // or 'String'
		  }
			
	  ]
});

npm run build:wundergraph

define a TaskList.graphql operation like:

query {
    dbpg_findManyTasksRemap {
        key
        field1
        field2 
        field3
    }
}

run the application and the server:

npm run start
