Swagger UI doesn't render t.Files() in body validation.

[besmillahibrahimi]

Hello there, I hope you are well.

I have a RESTful API written in Bun using Elysia. And I integrated @elysia-swagger. In one of my endpoints where I upload multiple files of the same fieldname and validate the body like below.

app.post("/", ({body}) => files, { body: { files: t.Files() } })

When I select application/form-data, while trying to upload files from Swagger UI, the exception is thrown. The error message is 😱 Could not render Parameters, see the console.

Error in console is SyntaxError: Unexpected token 'F', "Files" is not valid JSON

Thanks!

Hi, I have the same issue here as well. Using multipart/form-data request.

It is just a single file with t.File validation.

app.post(
    '/uploads',
    ({ body }) => body,
    {
        body: t.Object({
            digitalSignature: t.File({ type: ['image'] }),
        }),
    }
)

On me, it fails to validate and throw this error.

Invalid body, 'digitalSignature': Expected kind 'File'

Expected {
  "digitalSignature": "File"
}

Found: {
  "digitalSignature": {}
}

Can anyone provide solution for this?

For your case. You have as the following.

app.post( '/uploads', ({ body }) => body, { body: t.Object({ foo: t.File({ type: ['image'] }), }), } )

the issue with t.Files is that swagger-ui / scalar can't handle these default and elysiaMeta properties within the generated json:
