It appears that since 5.8.1 our bamboo instance is creating garbled text when it spins up an elastic-build agent, this doesn't appear to be damaging our builds but facter is reporting an error on many of our builts:
Fact resolution fact='ec2_userdata', resolution='rest' resolved to an invalid value: String "\225XY[trimmed]5\357\377\000" is not valid UTF-8
On looking at the userdata in the ec2 console the data is obviously not a readable UTF-8 string as expected, its all garbled.
How can i debug this?
