LLDP Rest API not returning all data

[mhult]

WB.16.10.0017, HP J9729A 2920-48G-POE+ Switch but also observed on other mothels and firmware.

When I run a "show lldp info remote-device 36-37" on the cli I get output from 2 devices (more lldp devices exist on the switch but left out for the example):

switch# show lldp info remote-device 36-37

However when I request the REST output from https://switch/rest/v7/lldp/remote-device I only get the output from port 36:

$response = Invoke-RestMethod "https://switch/rest/v7/lldp/remote-device" -Method "GET" -Headers $headers 
Foreach ($lldp_remote_device_element in $response.lldp_remote_device_element) {
$lldp_remote_device_element
}

device=False; station_only=False}
remote_management_address : {}
poe_plus_info : @{requested_power_in_watts=0.0; actual_power_in_watts=0.0}

I do not understand why port 37 is left out of the output. I fact, we have about 130 devices like port 36 but this is the only one that shows up in de REST output of all switches?

Other devices which have no issues are on same software version?

Thanks!
