odd alert nvme error "The transport type is not indicated or the error is not transport related"

[borissh1983 at gmail.com]

Hi, 

I'm struggling to get what could mean this odd "The transport type is not indicated or the error is not transport related" error inside nvme error-log which is filling my error log.
I also get smart warning of increasing num_err_log_entries , it look like it could correspond to one error for each boot but I do not grasp what could that mean.

I don't see any noticeable problems for now other than this alert. 

output form error-log have errors like this  : 
sudo nvme error-log /dev/nvme0

................. 
Entry[63]    
................. 
error_count     : 0 
sqid            : 0

cs              : 0 
trtype_spec_info: 0 
.................


This type of error is the same and fill each error entry.

my smart log for it is :
