[QUESTION]: Facing this error while running master code on my device

[shiv50084]

I am using latest commit 0550dba from master branch.

If i am setting log_level

export AWS_KVS_LOG_LEVEL=LOG_LEVEL_VERBOSE

at this time this error occurs and not able to stream.
Can you please check same thing happen with linux system also.

I tried to set log level bcz sometimes master not able to connect with viewer sometimes from linux system as well as from embedded device .For make it working i need to restart master again.

There are two questions:

1. Why the logs are not set
2. The root cause of the error

Exporting the variable should have set it to verbose. I am not certain why it didn't pick up. You could set the logging level directly in your application as well - take a look at how it's done in the sample. Perhaps, the log level gets overwritten by the signaling client.

For #2 you are getting 0x40000002 trying to create a peer which then causes 0x00000001 (NULL param). 0x40000002 is defined as STATUS_INVALID_BASE in PIC utils and it is generated when the underlying low-level string to integer conversion routine fails.

I think what you are trying to do is you are setting the log level to a string literal "LOG_LEVEL_VERBOSE" and the sample fails to parse as a number. You can either enhance the sample application to map the enums or simply specify

export AWS_KVS_LOG_LEVEL=1
