Problem with command 'clear cli logical-system' on JUNOS

[jakovlev54]

Hello, Carl!

Can you help me find out why in Scrapli, when using the "clear cli logical-system" command, a line break occurs after the word "cli"?

Fragment of scrapli.log:

            result = await conn.send_command("show route instance MMM")

This command is required to exit the logical system to the main device.

When entering commands manually everything is ok:

no idea! but we almost certainly aren't sending an extra newline just for fun!

I don't Junos but seems like you're upsetting it somewhere/someway (maybe in some previous command??) based on the syntax error output. Logs look like we correctly write it and then the error is pointing to the "cli" or after the cli part. is complete on space not disabled maybe for some reason? is there "more" to that command -- like "clear clis logical-system" or something?

JUNOS responds ambiguously - reason is again in authorization. Thanks for the answer!
