Supabase

​

Prerequisites

• A Supabase project on the Pro, Team, or Enterprise plan. Supabase offers log drains on these plans only.
• An ingest key. See Create an ingest key.

​

Set up the drain

1. In Supabase, open Project Settings and select Log Drains.
2. Add a destination of type OpenTelemetry (OTLP).
3. Set Endpoint to https://ingest.squasher.ai/v1/logs.
4. Set Protocol to http/protobuf. You can turn on Gzip: Squasher reads gzip OTLP bodies.
5. In Headers, add x-squasher-key with your ingest key, then save the drain.

What Squasher keeps from each record

​

Report Edge Function errors

const endpoint = `https://ingest.squasher.ai/v1/ingest/${Deno.env.get("SQUASHER_PROJECT_ID")}`;

Deno.serve(async (request) => {
  try {
    return Response.json(await handleCheckout(request));
  } catch (error) {
    const err = error instanceof Error ? error : new Error(String(error));
    await fetch(endpoint, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        "x-squasher-key": Deno.env.get("SQUASHER_API_KEY")!,
      },
      body: JSON.stringify({
        message: err.message,
        type: err.name,
        level: "error",
        stack: err.stack,
        environment: "production",
        tags: { service: "checkout" },
      }),
    });
    return new Response("Internal Server Error", { status: 500 });
  }
});

​

Verify

1. Select Logs in the sidebar in Squasher. Logs from your Supabase project appear there.
2. Make the Edge Function throw once.
3. Select Issues in the sidebar. The error is at the top of the list.

​

Limits

• The Supabase drain sends logs only. It does not send database metrics or traces.
• Which Supabase logs reach ERROR severity depends on Supabase.
