@mastra/aisdk 0.2.6 messaggeId duplicates

Using the

chatRoute

chatRoute

and

DefaultChatTransport

DefaultChatTransport

, I have an issue that did not exist in 0.2.4.
When I send a message, I get a SSE stream with the first chunk

{"type":"start","messageId":"ZTLXXeIMHJ3O1N1r"}

{"type":"start","messageId":"ZTLXXeIMHJ3O1N1r"}

. My Mastra agent then calls a tool provided by the client, and my client sends a response. This results in a new SSE stream (because of

sendAutomaticallyWhen

sendAutomaticallyWhen

), but that also has a first message with

{"type":"start","messageId":"ZTLXXeIMHJ3O1N1r"}

{"type":"start","messageId":"ZTLXXeIMHJ3O1N1r"}

. This seems like a bug to me, or has it been intentionally changed?

Relevant versions:

'@mastra/ai-sdk': 0.2.6
'@mastra/client-js': 0.16.9
'@mastra/core': 0.24.0
