An OmniStudio Developer attempts to deploy an Integration Procedure that calls a Remote Action Apex...

An Integration Procedure that calls a Remote Action depends on the referenced Apex class existing in the target org. If the Apex class is missing, the Integration Procedure cannot resolve that dependency during deployment or execution. The required fix is to deploy the Apex class first, then deploy the Integration Procedure that references it. Cache Duration has no relationship to metadata dependency resolution. Chainable configuration controls long-running transaction behavior and governor-limit handling, not missing Apex metadata. A Try-Catch Block can help handle runtime failures, but it does not solve a deployment failure caused by an absent Apex class. Salesforce’s OmniStudio deployment guidance specifically includes considerations for Apex class checks and dependencies when deploying Integration Procedures.
