Unhandled error in POST /file-upload: 500 Error: unknown format "binary" is used in schema at path "#/properties/file"
this is the error I am getting in console

@dip-sinha, please publish a GitHub repo sandbox with a minimum lb4 app so that we can replicate the issue and examine the code. Otherwise it may be difficult for us to pinpoint the issue.

@dip-sinha The example depends on #4808, which is merged into master but not published to npm yet.

There are two options to try this example now:

1. Check out strongloop/loopback-next github repo and run npm i under loopback-next to set up dependencies for examples/file-upload.

2. In the example application.ts, add the following code to the constructor:

this.bind(RestBindings.REQUEST_BODY_PARSER_OPTIONS)
  .to({validation: {unknownFormats: ['binary']}});
