How to Resolve "too_many_total_groups" Error with Amplitude Identify Call Using Segment?

Question

I am encountering an error when trying to use the identify function with Amplitude in combination with Segment. The tracking calls work correctly, but when I use identify, I receive a "too_many_total_groups" error. This issue occurs consistently with identify calls but not with tracking calls.

[{"body": "too_many_total_groups","headers": {"access-control-allow-methods": "GET, POST","access-control-allow-origin": "*","access-control-max-age": "86400","connection": "close","content-length": "21","content-type": "text/html;charset=utf-8","date": "Mon, 27 Nov 2023 11:36:47 GMT","strict-transport-security": "max-age=15768000","trace-id": "xxxx"},"statusCode": 400,"statusMessage": "Bad Request"}]

And here is the Python function I use for the identify call:

def identify(id, email, first_name, last_name):
    user_id = id
    company = parse_company_name(email)
    analytics.identify(
        user_id,
        {
            "email": email,
            "first_name": first_name,
            "lastName": last_name,
            "company": company,
            "created_at": datetime.now(),
        },
    )

My questions are:

1. What does the "too_many_total_groups" error indicate specifically in the context of using identify with Segment and Amplitude?

2. Are there known limitations or common issues with the identify function that could lead to this error, and how can I resolve it?

I've tried simplifying the userId to a standard format, and also ensured that my group types and properties are within the limits specified by Amplitude.
