So I have a simple POST request which takes a String as an option. The values are only "start" or "stop". Here is the function with its annotations : @POST @Timed @Operation( summary = "Turn off/on processing", requestBody = @RequestBody( description = "Processing state (off / on)", required = true, content = @Content( mediaType = MediaType.APPLICATION_JSON, schema = @Schema( implementation = String.class ), examples = { @ExampleObject( name = "start", value = "start" ), @ExampleObject( name = "stop", value = "stop" ) } ) ) ) @ApiResponses( value = { @ApiResponse( responseCode = "200", description = "Success response", content = @Content( mediaType = MediaType.APPLICATION_JSON, schema = @Schema(implementation = Boolean.class) ) ), @ApiResponse( responseCode = "400", description = "Bad request", content = @Content(mediaType = MediaType.APPLICATION_JSON) ) } ) public boolean switchProcessing(String state) { boolean ret; switch (state) { case "start" -> { // do something ret = true; } case "stop" -> { // do something else ret = true; } default -> ret = false; } return ret; } It produces this try it out : and this cURL : curl -X 'POST' \ 'http://localhost:15000/api/procedure-history' \ -H 'accept: application/json' \ -H 'Content-Type: application/json' \ -d '"start"' As you can see, there is quotes around the value. With this, the program don't recognize the String "start" so it doesn't enter in the correct switch case. If I remove the double quotes in the try it out, it produces this cURL and works as expected. curl -X 'POST' \ 'http://localhost:15000/api/procedure-history' \ -H 'accept: application/json' \ -H 'Content-Type: application/json' \ -d 'start' Do you have any idea on how I can fix it?
