Hello!
Content Manager does not support the ability to validate that reference lists and/or data tables are actually valid; The functionality to validate rule text is built into the tool already, making use of the verifyRuleText API endpoint, and there is a verifyReferenceList API endpoint as well.
For customers looking to build comprehensive detection as code CICD pipelines, it is imperative that we ensure that the files we are pushing into the SecOps platform are valid and do not fail syntax checks so that we do not break detections.
