Issue Summary

Hi team! I am working with Servicerocket in a ticket related to Confluence connect macros. They develop Scaffolding Forms & Templates and currently they have found an issue with their app.When filling one of their Field Group macros with a | (pipe character) anywhere in the body, getContentMacro fails to retrieve the data. They have added more details in the ticket but I could also replicate it with the same exceptions in my testing environment. My understanding is that not many customers would use a pipe character, however, when they do their Live Templates are rendered completely useless.

Please see these tickets and page for a full writeup (from the Connect team). The Connect team has passed this over to the Confluence team as it pertains to Confluence specific connector code:

Steps to Reproduce

Full reproduction steps can be found in the DEVHELP ticket: https://ecosystem.atlassian.net/browse/DEVHELP-7375

Expected Results

User can include a pipe character in their macro.

Actual Results

Trying to parse the JSON returned by `AP.confluence.getMacroData` fails with an `Unexpected end of JSON input` error, as the data returned is chopped off at where the pipe character was.

Workaround

Don't use the pipe character.
