BasicBubSub failing with code -1

[Deleted user]

Dear liuszeng,

I have installen AWS ioT SDK Version 2.2.0 on Arduino Yun as per instructions without any errors during the installation. I successfully uploaded example BasicPubSub, and it can successfully register, and then subscribe to "topic1" - no errors. After, it publishes the first message, it results in error -41, and the next message in error -1, as per below:

_AWS IoT SDK Version(dev) 2.2.0-

Publish failed!
-41
loop 0 done
Publish failed!
-1
loop 1 done
Publish failed!
-1
loop 2 done_

After that didn't work, I successfully upgraded AWSIoTPythonSDK to the latest version 1.2.0:

# pip install AWSIoTPythonSDK==1.2.0

I have uploaded BasicPubSub sketch again, and this time it couldn't even pass the setup:

_AWS IoT SDK Version(dev) 2.2.0-

Setup failed!
-1_

Could you please provide some guidance on how to solve this?

Regards,
Dennis
