Here is the first error in the RecorderEngine.log, it seems that I get hardware information failed.

Does this means there is an unhandled exception in MyConfigurationManager.FetchProductInformation()?

Or I give wrong information, cause the Driver framework throw this exception?

I have been trying to reproduce the situation, but have not been able to get into this failure state. Would it be possible for you to provide a version of the demo driver that is able to reproduce this error?

Thanks!

My DriverFramework Version is 2020R1, however It doesn’t appear in demo driver ever, just in my driver developed by DriverFramework by chance.

I have found an error in my code. Sometimes it cause the device disconnect from the recoding server ,but the Connection-State is still TRUE. After I fixed the error, it doesn‘t happen up to this time.

So, It seems that because I didn’t manage the Connection-State Well in my code.
