objects/rrdexport API No legend entry data

[norm_PH]

Since version 5.6.8, when I use the objects/rrdexport, I no longer have the Legend section filled

here's what I have:
{"meta"=>
{"start"=>"1574011200",
"step"=>"300",
"end"=>"1574011200",
"rows"=>"303",
"columns"=>"3",
"legend"=>{"entry"=>[{}, {}, {}]}
},...

I'm not able to reproduce. What OS is XI installed on and what version of php is it running?

Please provide the full command you're running as well as the corresponding rrd file from /usr/local/nagios/share/perfdata/<hostname>/.
