stevenzwu edited a comment on issue #8665: [FLINK-12781] [Runtime/REST] include the whole stack trace in response payload URL: https://github.com/apache/flink/pull/8665#issuecomment-508198033 @StephanEwen that is a great point. I should have looked into what the test failure really means, instead of just increase the max content length in the test class. there are already a few test methods verify the max content length. I can get the maxContentLength config from `FlinkHttpObjectAggregator` ChannelHandler. However, I found it tricky to determine the truncation size, because there are some other byte overhead in the payload. e.g. for the `RestServerEndpointITCase`, the magic number seems to be 81. I will update PR with a 1 KB overhead buffer. Let me know if you have any other suggestion. ``` FlinkHttpObjectAggregator flinkHttpObjectAggregator = ctx.pipeline().get(FlinkHttpObjectAggregator.class); String stackTrace = Ascii.truncate(ExceptionUtils.stringifyException(rhe), flinkHttpObjectAggregator.maxContentLength() - 81, "..."); ```
