Custom ID in Keystone 6

[ksemanur8]

My team built a database with Keystone 6 and we would like to put custom values in the ID field of our tables.
To give some more context, we have a table called Projects. This table has a ProjectId field, which is defined as such:

projectId: text({
        validation: { isRequired: true },
        isIndexed: "unique",
      }),

This field has all the properties we would want from a primary key for the table, so we find the auto-generated ID field unnecessary, and would like to customize it to be the same as projectId.
Here's how it looks on the Admin UI (Item ID is the auto-generated value).

Based on some discussions about this topic I found from Keystone 5 days, I've attempted setting an id field in our schema using the following syntax

fields: {
   id: ....
}

However, I received this error:

I also tried the idField option but found that it just makes a new field instead of controlling values in the pre-existing id field.

Is there another way of customizing the ID field?

Hi @ksemanur8,

Did you review the Custom ID example?
Although I conceptually agree with your intuition that id should be listed under fields, the current versions of @keystone-6/core don't support that.
