🐛 Bug Report: API request content-length is limit to 100KB

[hunghvu]

📜 Description

Right now, Novu API can only accept request size 100 KB at most. A simple trigger event is around 70 KB, but with attachments, it can easily exceed 100 KB, leading to code 413 Payload too large.

Not a NestJS expert, but I think the code below does not initialize Nest App with correct bodyParser and rawBody configuration, leading to an unexpected behavior.

novu/apps/api/src/bootstrap.ts

Line 63 in 0269ddc

bodyParser: false,

Quick NestJS reference: https://docs.nestjs.com/faq/raw-body#body-parser-size-limit

👟 Reproduction steps

Use a simple trigger event with attachments.

await novu.trigger("workflow-id", {
  to: "subscriber-id",
  payload: {
    // Practically total file size is limit around 30 KB, because the request itself is around 70 KB.
    attachments: [bufferData] 
  }
}) 

👍 Expected behavior

There are 2 possible ways.

1. Allow a safe, fixed limit for an API request size.
2. Expose a configuration (e.g., via environment variable), so developers can customize limits on their own. Why? Each notification/message provider has their own size limit, so developers can set the limit at their own judgment. For example, Gmail is capped at 25 MB per request.

👎 Actual Behavior with Screenshots

Here is a sample error emitted by Novu API service.
