how can we use expect command inside if loop in shell script - shell

Question

I have a set of commands to install my product. The installation process shoots up a few prompts. The problem is we have 2 versions of the product and the prompts are different during installation of each of these.
I have put a if condition and added expect inside it. But the script keeps failing.
#!/bin/bash
#In this mode any command this script runs which returns a non-zero
exitcode - an error in the world of shell - will cause your script to
itself terminate immediately with an error.
set -e
set -x
#Below varibles is used to set flag '0=Stage Pass' and '1=Stage Fail'
f="Fail" gotoStage="Pass" sdiclistage="Pass"
# An error exit function
error_exit()
{
echo "$1" 1>&2
exit 1
}
# Using error_exit : Goto data insight folder
if cd /opt/datainsight/; then
echo "inside /opt/datainsight directory."
else
{
error_exit "Cannot change directory! Aborting."
gotoStage=$f;
}
fi
echo "Worker ip: $1"
echo "NMS ip: $2"
echo "DI tar name: $3"
echo "DI version: $4"
echo "executing sdi-cli cluster command"
if [[ "1.5.3" == "1.5"* ]];
then {
echo "inside compa"
/usr/bin/expect <<EOD
set timeout 600
spawn sdi-cli cluster provision -y
expect {
timeout { send_user "\nFail to get password promt\n"; exit
1 }
"password for pwd:"
}
send "pwd\r";
expect {
timeout { send_user "\n Fail to continue connecting \n";
exit 1}
"Are you sure you want to continue connecting"
}
send "yes\r"
expect {
timeout { send_user "\n Fail to get second password promt
\n"; exit 1}
"password for pwd:"
}
send "pwd\r"
expect {
timeout { send_user "\n Error for completing provision\n";
exit 1}
"Provisioning complete."
}
EOD
echo "\nOutside sdi-cli cluster provision\n";
}
else
{
echo "In else"
/usr/bin/expect <<EOD
set timeout 600
spawn sdi-cli cluster provision -y
expect {
timeout { send_user "\n Fail to continue connecting
\n"; exit 1}
"Are you sure you want to continue connecting"
}
send "yes\r"
expect {
timeout { send_user "\n Error for completing provision\n"; exit
1}
"Provisioning complete."
}
EOD
echo "\nOutside sdi-cli cluster provision\n";
}
fi
if [ $? = 1 ]; then
{
echo "\nError for executing sdi-cli script\n";
sdiclistage=$f;
}
else
{
echo "\n sdi-cli script executed successfully\n";
}
fi
if [ $gotoStage = "Pass" ] && [ $sdiclistage = "Pass" ] ; then
{
echo "PASS" >> result.txt
echo "\n All installation stages Passed\n ";
}
else
{
echo "FAIL" >> result.txt
echo "\n All/Some installation stages failed \n";
}
fi
sleep 300 #5min
ui=$(kubectl get pods |grep ui |awk '{print $1}') #get ui pod name
kubectl exec -it $ui cat GITINFO.json >>buildinfo.txt
echo "\n Build info file created successfully";
This always fails with
echo 'DI version: 1.5.3'
+ echo 'executing sdi-cli cluster command'
