function-orchestrator code can be found at https://gerrit.wikimedia.org/g/mediawiki/services/function-orchestrator
Look in src/utils.js, isGeneric.
This should use the GENERIC validator from function-schemata.
This may occasion changes to the schema itself (function-schemata:data/NORMAL/GENERIC.yaml).
A good first task is a self-contained, non-controversial task with a clear approach. It should be well-described with pointers to help a completely new contributor. Given the non-existing task description and the lack of information where to find the codebase I'm removing the good first task tag. Please add details what exactly has to happen where and how for a new contributor, and then add back the good first task project tag. Thanks a lot in advance.
