-r[0 | 1]
Redirects the error message output to the screen (stderr). If you do not 
specify a parameter or if you specify 0, only error messages that have a 
severity level of 11 or higher are redirected. If you specify 1, all 
error message output including PRINT is redirected. Has no effect if you 
use -o. By default, messages are sent to stdout.

(source: 
https://docs.microsoft.com/en-us/sql/tools/sqlcmd-utility?view=sql-server-ver16) 



Conclusion: Do not use `-r 0` because of "if you specify 0, only error 
messages that have a severity level of 11 or higher are redirected."
