except command seems to be not executed via ssh - expect

Question

I learn how to use expect and I can't run any command (in this case pwd) in a remote host.
script:
#!/usr/bin/expect
spawn ssh ibmcoll#192.168.1.100
expect "Enter passphrase for key '/home/ibmcoll/.ssh/id_rsa': "
send passphrase\r
expect "*ibmcoll*"
sleep 3
send "pwd\r"
sleep 3
send "exit\r"
output:
expect ssh.exp
spawn ssh ibmcoll#192.168.1.100
Enter passphrase for key '/home/ibmcoll/.ssh/id_rsa':

[ibmcoll#servername ~]$
Where this script fails?
When run expect -d script.sh let me only post the most important part:
expect: does "\r\nLast login: Thu Feb 16 21:32:06 2023 from servername.domain\r\r\n************************************************************************************\r\n* This system should be used for conducting ####### business *\r\n* or for purposes authorized by ####### management it is mandatory *\r\n* to comply with all the requirements listed in the applicable security policy *\r\n* and only process or store the data classes approved for this *\r\n* asset type use is subject to audit at any time by ####### management *\r\n************************************************************************************\r\n\u001b]0;ibmcoll#servername:~\u0007\u001b[?1034h[ibmcoll#servername ~]$ "

send: sending "exit\r" to { exp4 }
