Flow Designer giving error cannot display all inputs for this action.

[RachitC]

We were in Vancouver Version and Flow were working fine. But after upgrade to Yokohama Version flow designer is giving error, "Cannot display all inputs for this action. Action exceeds 40 inputs." Also we have tried with attached system properties but not luck.

From the Docs page: https://www.servicenow.com/docs/bundle/yokohama-build-workflows/page/administer/flow-designer/concep...

"Limit dynamic inputs type inputs to 40 input values A dynamic inputs type input can only render a certain number of inputs before the JSON object becomes to too big to store in memory. Limiting your dynamic inputs to 40 input values minimizes the chances that you will run out of memory and experience unexpected behaviors such as rendering errors or data truncation."

It would seem that currently ServiceNow is enforcing this recommended limit of 40 instead of it just being a recommendation.  Not sure at this time if there is a way to increase the cap, may need to open a support ticket to see if something can be done for the Salesforce spoke to work with more options as that seems to be the norm in Salesforce environments.
