> Parameter Provider bundle version fallback not applied during flow import

> Key: NIFI-15547
> URL: https://issues.apache.org/jira/browse/NIFI-15547
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Pierre Villard
> Assignee: Pierre Villard
> Priority: Major
> Fix For: 2.8.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> When importing a flow (via upload, paste, or creating a versioned process
> group) that references a Parameter Provider with a bundle version not
> available in the system, NiFi fails to create the Parameter Provider even
> when only one compatible version is available.
> For processors and controller services, NiFi applies fallback logic via
> discoverCompatibleBundles() to resolve to an available bundle version.
> However, this method was not being called for Parameter Providers during flow
> import operations in ProcessGroupResource.java.
> Impact: Parameter Providers referenced in imported flows are not created when
> their exact bundle version doesn't match, even though the component type is
> available with a different version.
> Fix: Add
> serviceFacade.discoverCompatibleBundles(flowSnapshot.getParameterProviders())
> calls alongside the existing
> discoverCompatibleBundles(flowSnapshot.getFlowContents()) calls in the proper
> code paths.
