First of all, your debugging is flawed. You want to pass arrays and hashes as references to Data::Dumper:

print Dumper \@executions, scalar(@executions);

Second, you are copying the reference into @executions, not the contents. This means that @executions will only ever contain a single element:

my @executions = $jobInfo->{'content'}{'executions'};

What you likely wanted is to copy the array items:

my @executions = $jobInfo->{'content'}{'executions'}->@*; # requires P
+erl 5.36+

# Alternatively

my @executions = @{ $jobInfo->{'content'}{'executions'} };
