#InterSystems Package Manager (IPM)

Hi - I'm refreshing my IRIS instance, now upgraded to 2025.1, and ensuring IPM is installed in each namespace, as well as git-source-control, but in my first attempt I get this error. 

Everything else seems to work - but why the error (I'd like to get rid of it) ?

zpm:AULIBRARY>install git-source-control
 
[AULIBRARY|git-source-control]  Initialize START
[AULIBRARY|git-source-control]  Initialize SUCCESS
[AULIBRARY|git-source-control]  Reload START (C:\InterSystems\IRIS\mgr\Temp\VTigyGg\)
[AULIBRARY|git-source-control]  Reload SUCCESS
[git-source-control]    Module object refreshed.

I have a custom IPM resource processor like:

<Resource Name="example.json" ProcessorClass="OSEX.ipm.demo.IpmResourceProcessor" Foo="from manifest Resource attribute"/>

What is the best practice to deploy the custom resource processors to the IRIS instance? It can't be part of the module that uses it for obvious (?) chicken-egg situation.

My best idea atm is to put all those custom processors into a (library) module and all modules using any of them just have a dependency to the custom processors module.
