Mark Payne commented on NIFI-11627:
-----------------------------------
[~nwchuckster] yes, the approach that you mentioned there, which uses
{{evaluateELString}} was an oversight that has since been patched. Anywhere
that you're using that, you'll want to fix because in more recent versions that
will fail.
> Add Dynamic Schema References to ValidateJSON Processor
> -------------------------------------------------------
>
> Key: NIFI-11627
> URL: https://issues.apache.org/jira/browse/NIFI-11627
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.19.1
> Reporter: Chuck Tilly
> Assignee: Daniel Stieglitz
> Priority: Major
>
> For the ValidateJSON processor, add support for flowfile attribute references
> that will allow for a JSON schema located in the Parameter Contexts, to be
> referenced dynamically based on a flowfile attribute. e.g.
> {code:java}
> #{${schema.name}} {code}
>
> The benefits of adding support for attribute references are significant.
> Adding this capability will allow a single processor to be used for all JSON
> schema validation. Unfortunately, the current version of this processor
> requires a dedicated processor for every schema, i.e. 12 schemas requires 12
> ValidateJSON processors. This is very laborious to construct and maintain,
> and resource expensive.
