Handling exceptions

If you want to handle a specific exception differently, you can do that inside the handle method. Make sure to use the ctx.response.send method to send a response, since the return value from the handle method is discarded.

API

import { errors } from '@jrmc/adonis-attachment'

export default class HttpExceptionHandler extends ExceptionHandler {
  async handle(error: unknown, ctx: HttpContext) {
    if (error instanceof errors.E_CANNOT_WRITE_FILE) {
      const err = error as errors.E_CANNOT_WRITE_FILE
      ctx.response.status(422).send(err.messages)
      return
    }

    return super.handle(error, ctx)
  }
}
