SSH on Cisco device throwing error - Unsupported shell 'IOS.sh''

We have a simple ssh command running on a cisco device to collect data (not Discovery, just regular SSH activity block). But it is erroring out -

Unsupported shell 'IOS.sh''. Supported shells are [tcsh, csh, ksh, sh, IOS.sh, bash], and Bourne compatible shells in that list are specified by 'mid.ssh.shells_supported' (defaults to [ksh,sh,bash]).

 

I have added the mid server param 'mid.ssh.shells_supported' to include all the supported values. But still getting error. The SSH command works directly from the mid server VM. It is just not working when run from ServiceNow via mid server.

 

Has anyone resolved this error ?

Are you using discovery probe to run the command or ssh step ?
if you are discovery probe add this parameter "allow_unsupported_shells "  and set it to true in the "Probe Parameters" related list.
