Flow Designer, unable to open action: This action cannot be foundIssue When you open an action in Flow Designer, an error is displayed: This action cannot be foundCauseThere are underlying database problems, a common cause is the use if restricted words in parameters of a step. To work this out, open sys_hub_step_ext_input. You can order by created or dated, you can also use the field 'model' to find the action. ResolutionLook for values of 'Column Name', a common problem is using sys_id, which is restricted and causes database issues. You can call it sysid but not sys_id. If that's the case you need to remove the record.
