Error in REST request after VPLEX upgrade

Hi,

last week we upgraded one of our VPLEX's GeoSynchrony from version 5.4.1.03.00.04 to version 6.0.1.06.00.03.

after the upgrade one of our monitoring scripts doesn't work anymore with the upgraded VPLEX, but it works fine with the non-upgraded one.

the script issues a REST POST request using curl to get details from the machine.

this is the curl command:

curl -K /root/.curl.cfg -g -d '{"args":"-l /engines/engine-1-1/directors/director-1-1-A/hardware/sfps"}' -X POST https:// /vplex/ls

for some reason, this is the output i receive:

Exception:

  Invalid URI in POST request. Not one among context,command or attribute.

if i run the same command in the non-upgraded VPLEX, i get the desired output:

/engines/engine-1-1/directors/director-1-1-A/hardware/sfps:

i tried to make some adjustments from another topic - Correct CURL/REST payload data to invalidate cache for a consistency group but to no avail

so now i wanted to ask the help from the masses, 2 (billion) brains are better than 1

any suggestions?
