Validator error should specify source (line no. or calling function)

The error message does not tell you where the issue is (line or calling function)

This is the offending code:

export const marketSegmentsWorkflow = workflowManager.define({
  args: {
    companyId: v.id('company'),
    mainDetails: mainDetailsConvexObject,
  },
  returns: v.array(v.string()),
  handler: async (step, args): Promise<string[]> => {
    const existingSegments = await step.runQuery(
      market_analysis.db.getMarketSegmentsInternal,
      args,                                         <---------------- HERE
    );

  ...
});

This is not easy to catch, as there are no linting or build errors and the error message does not point to anywhere in the source code.
