## Description

This is a Group MMS conversation, but the given participant has neither an Address nor a ProjectedAddress.

### Possible Causes

- You may have inadvertently provided an Identity (chat user), rather than an Address (mobile phone).
- You may have mistyped or inadvertently left out the ProjectedAddress parameter.

### Possible Solutions

- [Provide a Projected Address](/docs/conversations/group-texting#scenario-1-set-up-a-group-message-with-one-chat-participant-and-two-sms-participants) when adding this Participant to the Group Conversation. This is the correct path when adding Chat participants to a Group MMS conversation.
