@Override
public ResponseEntity<InputStreamResource> exportfooAsPdf(@PathVariable("id") UUID id) {

I’m getting this error for InputStreamResource

‘exportfooAsPdf(UUID)’ in ‘de..web.controller.fooSearchController’ clashes with ‘exportfooAsPdf(UUID)’ in ‘de..web.controller.FooApiDelegate’; attempting to use incompatible return type

I replaced InputStreamResource with Resource and it still didn’t work
