Stephanie Ambrose updated NIFI-12918:
-------------------------------------
Description:
If you create a process group and commit that to version control, and then add
a sub-process group under that one and commit that to its own version control,
it will throw a NullPointerException:
*NOTE: This error only occurs for stateless nifi processing.*

Looking further, it appears the "storageLocation" property is actually the
dependency that is used for the sub-getFlow calls. I submitted the PR to change
the non-null requirement to storageLocation for this reason. The sub-call in
1.x (1.25 tested) also uses the wrong "getRegistryUrl" method, which was
changed to "getStorageLocation" on the main branch. Making these two changes
fixes the versioned PG bug in stateless NiFi. Ultimately, it looks like
VersionedFlowCoordinates are not mapped from the JerseyClient call correctly.
This is not done directly from the JSON returned from the registry-api call.
(I'm not sure where that's done)...but with other places showing "registryId"
as "placeholder", I'm assuming this is something still in "to do" status.
was:
If you create a process group and commit that to version control, and then add
a sub-process group under that one which is also under a separate version
control, it will throw a NullPointerException.

> Looking further, it appears the "storageLocation" property is actually the
> dependency that is used for the sub-getFlow calls. I submitted the PR to
> change the non-null requirement to storageLocation for this reason. The
> sub-call in 1.x (1.25 tested) also uses the wrong "getRegistryUrl" method,
> which was changed to "getStorageLocation" on the main branch. Making these
> two changes fixes the versioned PG bug in stateless NiFi. Ultimately, it
> looks like
> VersionedFlowCoordinates are not mapped from the JerseyClient call correctly.
> This is not done directly from the JSON returned from the registry-api call.
> (I'm not sure where that's done)...but with other places showing "registryId"
> as "placeholder", I'm assuming this is something still in "to do" status.
