As reported in #21146
The exception trace might contain instances that will fail if passed to
json_decode
while rendering the response, this will cause an exception to be thrown preventing a proper response from being produced.In this PR, we only render the
file
,line
,function
,class
, andtype
from each trace, these values are always strings/integers whileargs
might hold objects that are un-decodable.
