Value does not match validator

I pass a convex id as an URL params. This URL params i use to make a query to get other list of data. What i wanted to do was if someone tried to modify the URL say it doesnt exist but i get the convex error. Any solution as to why this happens ?

You can use validator v.string() and check yourself in the function with ctx.db.normalizeId and/or ctx.db.get

i dont quite understand i know i am sending invalid id, what i want is to make a query and then reutrn error message that it doesnt work. Currently it crashes when i query with invalid query instead of giving me doesnt exist error

yes i think i understand. instead of subjectId: v.id("subjects") do subjectId: v.string(). Then in your function do const subject = await ctx.db.get(args.subjectId); and then if (subject === null) throw new ConvexError("invalid subject")

Are you still seeing this error? What does your args validator look like?

@uzamaki21 - you can cast your URL parameter as required. This is how I do the same thing (using tanstack router & tanstack query in this example):

function CampaignsEdit() {
  const { data: campaign } = useSuspenseQuery(
    convexQuery(api.campaigns.queries.getCampaign, {
      id: Route.useParams().campaignId as Id<"campaigns">, // <-- this makes the validator happy
    })
  );

  return <CampaignEditor campaign={campaign} />;
}

function CampaignsEdit() {
  const { data: campaign } = useSuspenseQuery(
    convexQuery(api.campaigns.queries.getCampaign, {
      id: Route.useParams().campaignId as Id<"campaigns">, // <-- this makes the validator happy
    })
  );

  return <CampaignEditor campaign={campaign} />;
}
