### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened When I try to set Custom Parameters of SQL Task Node with OUT type, I get such error msg: ``` [ERROR] 2022-06-10 09:32:40.206 +0000 org.apache.dolphinscheduler.spi.utils.JSONUtils:[215] - json to map exception! com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.lang.String` out of START_OBJECT token at [Source: (String)"{"id":1,"code":5791423019648,"name":"cat","version":1,"description":"","project_code":5791415412992,"release_state":1,"user_id":1,"global_params":"[]","flag":1,"locations":"[{\"taskCode\":5791416706432,\"x\":-5.5,\"y\":147.5}]","warning_group_id":null,"timeout":0,"tenant_id":-1,"execution_type":0,"create_time":{},"update_time":{}}"; line: 1, column: 313] (through reference chain: java.util.LinkedHashMap["create_time"]) at com.fasterxml.jackson.databind.exc.MismatchedInputException.from(MismatchedInputException.java:59) at com.fasterxml.jackson.databind.DeserializationContext.reportInputMismatch(DeserializationContext.java:1445) at com.fasterxml.jackson.databind.DeserializationContext.handleUnexpectedToken(DeserializationContext.java:1219) at com.fasterxml.jackson.databind.DeserializationContext.handleUnexpectedToken(DeserializationContext.java:1129) ``` In msg, `create_time` had wrong value `{}`. Thought debug, I found sql task Convert datatime to LocalDateTime. And then, JSONUtils parse this LocalDateTime object to `{}`. I write test case, this situation is reproduced: ``` @Test public void localDateTimeToString() { TimeZone.setDefault(TimeZone.getTimeZone("Asia/Shanghai")); String time = "2022-02-22 13:38:24"; Date date = DateUtils.stringToDate(time); LocalDateTime localDateTime = LocalDateTime.ofInstant(date.toInstant(), ZoneId.systemDefault()); String json = JSONUtils.toJsonString(localDateTime); // console print: {} System.out.println(json); Assert.assertEquals(json, "\"" + time + "\""); } ``` ### What you expected to happen JSONUtils parse LocalDateTime object to correct value. ### How to reproduce Run the above test case. ### Anything else _No response_ ### Version 3.0.0-beta-1 ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
