document.list() returns 500 error when filtering by instanceId

[shotainoguchi]

Describe the bug
When calling document.list() and specifying instanceId as a filter, a 500 error is returned.

To Reproduce
Execute the following code:

client.documents.list({
  filter: {
    equals: {
      property: ["instanceId"],
      value: {
        externalId: "377471e4-c9cf-4a3b-9e35-49981c8b576a",
      },
    },
  },
  limit: 1000,
});

You will see an 500 error Internal server error. Please contact Cognite.

• The DocumentFilterValue follows the Label interface, which results in {externalId: "your externalId"} based on its definition.

Expected behavior
I was able to get a valid response with this request:

client.post(
  `/api/v1/projects/${PROJECT}/documents/list`,
  {
    data: {
      filter: {
        equals: {
          property: ["instanceId"],
          value: {
            space: "File_Search",
            externalId: "377471e4-c9cf-4a3b-9e35-49981c8b576a",
          },
        },
      },
      limit: 1000,
    },
  }
);

In my humble opinion, we should create a new interface instead of Label interface for example:

cognite-sdk-js/packages/stable/src/api/documents/types.gen.ts

Line 761 in c278e56

export interface Label {

export type CogniteExternalId = string;
export type CogniteSpace = string;
export interface Instance {
  externalId: CogniteExternalId;
  space: CogniteSpace;
}
