# 530001: Profile resolution skipped

Log Type: TWILIO

Log Level: WARNING

## Description

Profile resolution was not attempted for this participant. This occurs when the participant type does not support profile resolution or when the participant's address cannot be mapped to a valid identifier.

### Possible causes

* The participant isn't a `CUSTOMER` type (e.g., `HUMAN_AGENT` or `AI_AGENT` participants don't undergo profile resolution).
* The participant's address type doesn't map to a supported identifier (e.g., chat addresses like `client:alice` have no phone or email identifier).

### Possible solutions

* This warning is informational and doesn't indicate a failure.
* If profile resolution is expected, verify the participant type is `CUSTOMER` and the address is a phone number, email, or WhatsApp identifier.
