I have exactly the same error

[Seungkoo]

I also have the same problem.

I have the same problem, did you find a solution?

[Seungkoo]

I found the solution for this problem.
API and model might be changed from ThingsBoard platform version 3.4.2. "Asset_profile" model was added and this change was applied to dart package "thingsboard_pe_client" v1.0.5.
Open the file "pubspec.yaml" in your project directory and change the version of thingsboard_pe_client from 1.0.4 to 1.0.5, recompile your project.

Thank you very much @Seungkoo, it works.

[ezeroldan24]

Thank you very much, it works fine @Seungkoo .

[badril1978]

works for me as well.

[ezeroldan24]

Does anyone know if there is a way to prevent this from happening again with new updates? Thank you.

[LokeshReddy63]

probably someone from thingsboard team has to take a pick and change the version on the pubsepec file may be... probably not sure how the development process is in thingsboard.
