Expect exiting, not responding to text sent

I have an expect script that is exiting, instead of processing text that is sent and installing files. I'm trying to figure out why it's not installing files, i.e. not implementing what would be done had I run the process manually instead of via expect.

I have the following code in my script:

#!/usr/bin/expectset exp_internal 1set timeout 30set java [lindex $argv 0];set installer [lindex $argv 1];spawn $java -jar $installer -consoleexpect {"*More*" { send " "; exp_continue }"Press 1 to accept, 2 to reject, 3 to redisplay" { send "1\r" }}expect "Select the installation path:*" { send "/opt/pentaho8.3\r" }expect "Press 1 to continue, 2 to quit, 3 to redisplay\r\n" { send "1\r" }closeexit

When I run the script as follows:

$ sudo /usr/bin/expect -d install-pentaho.expect /usr/java/jdk1.8.0_261/bin/java pentaho-server-manual-ee-8.3.0.0-371/installer.jar

It runs as expected, except for the last couple lines:

send: sending "/opt/pentaho8.3\r" to { exp6 }expect: does "" (spawn_id exp6) match glob pattern "Press 1 to continue, 2 to quit, 3 to redisplay\r\n"? no/opt/pentaho8.3expect: does "/opt/pentaho8.3\r\r\n" (spawn_id exp6) match glob pattern "Press 1 to continue, 2 to quit, 3 to redisplay\r\n"? noPress 1 to continue, 2 to quit, 3 to redisplay    expect: does "/opt/pentaho8.3\r\r\n\r\nPress 1 to continue, 2 to quit, 3 to redisplay\r\n" (spawn_id exp6) match glob pattern "Press 1 to continue, 2 to quit, 3 to redisplay\r\n"? yes    expect: set expect_out(0,string) "Press 1 to continue, 2 to quit, 3 to redisplay\r\n"    expect: set expect_out(spawn_id) "exp6"    expect: set expect_out(buffer) "/opt/pentaho8.3\r\r\n\r\nPress 1 to continue, 2 to quit, 3 to redisplay\r\n"    send: sending "1\r" to { exp6 }

Anyone have thoughts as to why the '1' being sent by expect is getting ignored? It seems that the spawned process is exiting, ignoring the '1' that is sent.

Below is the expected output, i.e. what I get when I run sudo /usr/java/jdk1.8.0_261/bin/java -jar pentaho-server-manual-ee-8.3.0.0-371/installer.jar -console manually:

Any thoughts on why the installation is not occurring, and the expect script is exiting prematurely?
