Failed to complete request: org.springframework.http.InvalidMediaTypeException: Invalid mime type "; charset=utf-8": 'mimeType' must not be empty

[sapessi]

Thanks for reporting this @1103036128. Do you have an example of the incoming request (event dump)? Also, make sure you are using the latest version of the framework: 1.3.2

[1103036128]

I found this problem: the aws lambda serverless container does not need to set the filter - response.SetCharacterEncoding (" utf-8 "), you can close this problem, thank you

[1103036128]

But I want to set the character encoding to utf-8,
where do I need to set this character encoding, am I using springboot configuration, or am I reporting an error.
#encoding
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
spring.http.encoding.force=true
server.tomcat.uri-encoding=UTF-8

[1103036128]

The error is:
Failed to complete request: org.springframework.http.InvalidMediaTypeException: Invalid mime type "; charset=utf-8": 'mimeType' must not be empty

[1103036128]

My dependency is :

com.amazonaws.serverless
aws-serverless-java-container-spring
1.3.1

[1103036128]

The 1.3.2 version is the same error:
Invalid mime type "; charset=utf-8": 'mimeType' must not be empty

[1103036128]

My example：

@RestController
@RequestMapping("/ordr/v1")
public class OrderController {
	private static final Logger LOGGER = LoggerFactory.getLogger(OrderController.class);

	@RequestMapping(value="/health",method=RequestMethod.GET)
	public Object health(String name,HttpServletResponse response){
		Map<String, Object> model = new HashMap<String, Object>();
		model.put("code", 200);
		model.put("message", "health心跳测试完成。可正常使用");
		LOGGER.debug("test /health RESTful api.");
		return model;
	}
}

@sapessi I hope you can help me with this problem. Thank you very much

[1103036128]

My springboot version is 2.1.4

[sapessi]

Thanks @1103036128 - I'll work to replicate today. This is the character encoding of the response correct?

[1103036128]

If I don't set the springboot configuration of utf-8, it will respond normally, but Chinese characters will be scrambled.So I want to set it to utf-8, but it will cause abnormal response
