why is the hash value missing in the below code

Question

I wanted to do a POST request to jira and jfrog. while I try to get the values of the hash within the loop am not able to get the value the second time. I try to read the variable(API token instead of password) from env, if not set it will pass the username and password.

my %urls = (
    'jira' => {
        'url' => 'https://jira.com:123/rest/api/2/issue/', 
        'token' => 'JIRA_TOKEN'
    },
    'jfrog' => {
        'url' => 'https://jfrog.com/artifactory/api/storage/path/to/artifacts',
        'token' => 'JFROG_TOKEN'
    }
);

my $jira_ua = Mojo::UserAgent->new();
for my $outer_elem ( keys %urls ) {
    for my $inner_elem ( keys %{$urls{$outer_elem}} ) {
        # print $inner_elem;
        if ( !$ENV{$urls{$outer_elem}{'token'}} ) {
            print "Enter username : \n";
            my $username = <STDIN>;
            chomp($username);
            my $passwd = read_password("Enter Password: ");
            $url = Mojo::URL->new($urls{$outer_elem}->{'url'})
            ->userinfo($username.':'.$passwd);
        }
        else {
            if ( $inner_elem eq "jira" ) {
                $tx->req->headers->authorization (
          "Bearer $ENV{$urls{$outer_elem}->{'token'}}"
               );
                $url = Mojo::URL->new($urls{$outer_elem}->{'url'})
            }
        }
        print $outer_elem . "\n";
        print "logging in to $urls{$outer_elem}->{'url'}\n";
        $tx = my $ua->get($url); # <--- line 170
        my $res = $tx->res->code;
        print $res;
        last;
    }
}

I get below output

D:\scripts>perl emtf.pl
jira
