Thanks @Li-Yanzhi for the bug fix in cost extraction. Pushed an update - v0.1.2

v0.1.2 still have the below same type error:

Thanks for noting this @huqianghui . The error suggests that a model client is not set on the receiver. Will add a check for this to fix. In the meantime, can you try setting summary method to last or none for your workflow or verify that the receiver agent indeed has a model associated with it.
