How to cut the output of grep command?

I am running a salt state and using grep to retrieve any checks that have failed. Upon every failure salt by default outputs the following text:

ERROR: Minions returned with non-zero exit code

I want to cut this output from my command so that I can use the actual failure (i.e, the details of which check failed) to be output to a .html file which will be used to display the current state of our environment.

Here is my command:

salt --state-output=terse -C 'ServerName' state.sls ldapchecker test=True | grep 'Result: Failed'

And here is the output:

ERROR: Minions returned with non-zero exit code 
Name: /var/log/stunnel.stunnel.log - Function: file.exists - Result: Failed

I would like to be left with just the path of the failed check (/var/log/stunnel.stunnel.log)

EDIT: As requested here is the output of:

salt --state-output=terse -C 'BCA-AJT-LD-01' state.sls ldapchecker test=True 2>/dev/null

Try this code:

salt --state-output=terse -C 'ServerName' state.sls ldapchecker test=True | grep 'Result: Failed' | awk -F':|-' '{print $2}'

If you want to use single command then awk could help here too.

your_command | awk '/^Name:/{print $2}'

EDIT: As per your latest edit could you please try following command.

your_command | awk '/Name:/ && $2 ~ /\// && $0 ~ /Result: Failed/{print $2}'
