NameValueGenerator is not thread safe - Known Error

NameValueGenerator is not thread safe Description This is a multithreading issue caused by the JSON Builder step. When executing many asynchronous JSON Builder steps across multiple different threads, several fields in the respective operation class, which are declared as static, will overwrite one another inevitably causing a NullPointerException. The exception will cause a failure in the action and all subsequent steps or actions will halt.

Steps to Reproduce

Install integrationhub enterprise pack Ensure Flow reporting is enabled, set to full or trace Open flow designer and create a new action Add the JSON Builder step, utilize the step and give it some example data Save and publish the action Create a code snippet of the action and paste it somewhere to be executed such as Background - Scripts Loop the execution of the script 100 times Open the executions page in flow designer and notice that several executions have a failure of NPE Workaround There is currently no workaround, hence we backported the fix to Xanadu Patch 3 and Washington Patch 9.
