This is a known issue for jackson: [https://github.com/FasterXML/jackson-core/issues/223] You can see more details: [https://github.com/FasterXML/jackson-core/blob/master/src/main/java/com/fasterxml/jackson/core/json/UTF8JsonGenerator.java#L2105] And I also encountered this issue in my production environment. I've figured out a solution to solve this issue. Java's String.getBytes() can deal with UTF-8 encoding well. So we can do it like this: {{mapper.writeValueAsString(node).getBytes()}} instead of {{mapper.writeValueAsBytes(node)}} cc [~jark] [~twalthr] -- This message was sent by Atlassian Jira (v8.3.4#803005)
