I am using a!startprocess function from an interface to save some data to db, now lets say the process model being called encounters a run time error in some node, i need to show the user some custom message like ' some error occured' in the interface , onError dosent work here , as there was no issue starting the process.

Using activity chaining, you can control at which step in the process the a!startProcess function returns. Did you try this?
havent tried this , but my understanding was the behavior of how onError works, from the Docs: "The onError parameter will only evaluate if the process fails to start. It will not evaluate if a node in the started process pauses by exception"
Sure, but with some clever design of process variables and value setting, you should be able to return such a message to the user when evaluating onSuccess.
Wait for a process response, as a variable.. and after that, with refresh variables, control the behavior of the interface, and depending on the value received from the process, show the message or not.
i see what you mean , let me try it out
This is an example that I like to refer to for handling errors with a startProcess in an API but the method would be very similar: https://community.appian.com/discussions/f/process/20396/status-code-of-a-webapi-to-start-process-model
