## Troubleshooting

### Why are my calls with trait arrays not showing up in Mailchimp?
#### Why are my calls with trait arrays not showing up in Mailchimp?
Mailchimp doesn't support arrays as traits values. This can cause calls to not show up.

### Why are there frequent 404 Bad Requests from Identify events without an error message?
If you send concurrent requests for the same userId, MailChimp blocks the events because MailChimp restricts each API key to a maximum of 10 concurrent requests.
#### Why am I seeing a `400 Bad Request` error?
A **400 Bad Request** error can occur if the email address contains a misspelled domain name. For example, Mailchimp might reject`"[email protected]"` because "gmail" is misspelled.

#### Why am I seeing frequent `404 Bad Request` errors from Identify events with no error message?

Mailchimp blocks concurrent requests for the same `userId` if they exceed its rate limit. Each Mailchimp API key allows a maximum of 10 concurrent requests, so sending multiple requests for the same user at the same time may result in `404 Bad Request` errors without a detailed error message.
