FAILED: /opt/CPotelcol/REST.py - Error: 'utf-8' codec can't decode byte 0xca in position 1: invalid

Hello,

running R81.10 + JumboHFA Take 110 and Skyline/CPOtelcol Verison Take 70 on Maestro

I get this error out of a sudden on the SGMs of the Maestro:
Further I get the same error on 1 out of 4 MHOs.

I checked md5sum and it is the same:

[Expert@l999ravpn101d-ch02-01:dplane]# g_md5sum /opt/CPotelcol/REST.py

I did "dos2unix" for REST-py and for the payload.json. Did not solve the issue. I use the same payload.json on other environments and it works.

[Expert@l999ravpn101d-ch02-01:dplane]# g_allc "cpinfo -y all | grep -i otel"

any ideas why this REST.py script does not work (anymore) ?

Hi @Alexander_Wilke , Please open a support ticket to CheckPoint, so we can assist you on this issue. Also, try the following:

1) On SMO - g_all /opt/CPotelcol/CPotelcolCli.sh set_dynamic_config $(cat /opt/CPotelcol/config.json)

2) Re - run the script

[Alexander_Wilke]

Hi,

unfortunately this is a "poc and Buy" environment and the PoC Team is mad, Diamond engineer has enough other topics and so the progress is slow and I can not open a ticket because appliances are not in the user center.

There is another ticket open for "config_verify -v" failed for cpotelcol. However this is another topic.

This file does not exists:
/opt/CPotelcol/config.yml

Instead there is the /opt/CPotelcol/config.json

Hi @Alexander_Wilke, 

Try to re run the command as following:

g_all '/opt/CPotelcol/CPotelcolCli.sh set_dynamic_config "$(cat /opt/CPotelcol/config.json)"'

[Alexander_Wilke]

Hello,

this fixed the issue on MHO

/opt/CPotelcol/CPotelcolCli.sh set_dynamic_config "$(cat /opt/CPotelcol/config.json)"

this fixed the issue on Maestro - the g_all command did not work:
gexec -b all -c '/opt/CPotelcol/CPotelcolCli.sh set_dynamic_config "$(cat /opt/CPotelcol/config.json)"'


After that I could re-run successfully on MHO and SMO.
/opt/CPotelcol/REST.py --set_open_telemetry "$(cat /home/admin/skyline_payload.json)"


You should add this to the SK and/or fix it with the next update packages.

Thanks you Sir. save my day, that's worked for me too.

I ran this one:

/opt/CPotelcol/CPotelcolCli.sh set_dynamic_config "$(cat /opt/CPotelcol/config.json)"

and this after :

/opt/CPotelcol/REST.py --set_open_telemetry "$(cat payload.json)"

And worked!
