Error on zenpacklib --create command

[vikt0rs]

Hi folks,

I'm trying to create a new ZP using documentation from https://zenpack-sdk.zenoss.com/en/latest/getting-started.html but I'm getting a strange exception during the command run. Please find trace below

[zenoss@domain ~]$ zenpacklib --create ZenPack.zenoss.PS.EMCXtremIO

ok, the quick debug showed, that the error was in initial ZP name - ZenPack.zenoss.PS.EMCXtremIO not ZenPacks.zenoss.PS.EMCXtremIO. Should this be handled in some way?

@vikt0rs: Yes. Validating that the name starts with ZenPacks. sounds like a good idea. I had to look at the error for quite a while even after you explained what it was to realize it was a missing s.

@cluther ok, I'll prepare a PR to handle this situation, if nobody minds
