Hi out there we changed from REHL7 to RHEL8, perl5.10 to 5.26 and unfortutately our ES-Scripts does not work anymore. Have any of you ever seen something like this before? Cheers Jens

@jenswitzel sorry for the delay, did you solve the issue? I think this is related to some encoding issue with the allow_blessed of the JSON library. Are you building a JSON request or this error is in the HTTP response?

[jenswitzel]

@ezimuel yes, solved it. Due to Upgrade to RHEL8 we also upgraded to perl5.26.3 and had to fix our JSON answer. Must be something like this now:

[...]
# push result to browser
binmode( STDOUT, ":utf8" );
print header('application/json');
#  new Perl, new to_json
my $s = JSON::to_json($result, { allow_blessed => 1, allow_nonref => 1 });
print $s;
[...]
