The field must be a UTF-8 encoded string with a length limit of 1,000
characters. Otherwise, an INVALID_ARGUMENT error is returned.
This should not be set when using the client side event reporting with
GTM or JavaScript tag in
[UserEventService.CollectUserEvent][google.cloud.discoveryengine.v1beta.UserEventService.CollectUserEvent]
or if
[UserEvent.direct_user_request][google.cloud.discoveryengine.v1beta.UserEvent.direct_user_request]
is set.
Highly recommended for logged-in users. Unique identifier for logged-in
user, such as a user name. Don't set for anonymous users.
Always use a hashed value for this ID.
Don't set the field to the same fixed ID for different users. This mixes
the event history of those users together, which results in degraded
model quality.
The field must be a UTF-8 encoded string with a length limit of 128
characters. Otherwise, an INVALID_ARGUMENT error is returned.
