Process plan JSON isn't serialized properly due to infinite recursion (gets truncated) and consequently there's an unexpected end-of-input when it's deserialized - Known Error

Process plan JSON isn't serialized properly due to infinite recursion (gets truncated) and consequently there's an unexpected end-of-input when it's deserialized Description Setting a script of output type String to something other than a string can cause infinite recursion in serialization (we've seen this with XMLDocument2 and Javascript dates).

Steps to Reproduce

Install attached update set sys_remote_update_set_74efc788db3d1010542ae8cd139619f1.xml Run RecursiveSerializationFlow using the Test button

demonightlyorlando: the flow gets stuck and doesn't indicate there's an error even though it's there in the logs demonightlyus: flow does error out and error below is captured in the flow logs, but it would be more helpful if it actually told us where the error occurred

Workaround Force the output to a string by changing:

outputs.output1 = new Date();

to:

outputs.output1 = new Date().toString();
