Issue Summary

When integrating automation with JEC, it's possible to send a callback to the rule with custom data after the script execution. 

Currently, this is limited to 4096 bytes so if you try to send back a lot of data it can result in a broken pipe error.

BrokenPipeError: [Errno 32] Broken pipe 

Steps to Reproduce

1. Create an integration with JEC using automation.
2. Add a script on the server side to send a callback.
3. Run the rule.

Expected Results

To be able to send large payloads to automation.

Actual Results

Not able to send a payload beyond 4096 bytes

Workaround

Currently, the workaround is to restrict the content sent and send only what is necessary to stay within size limit
