The option to create new variables becomes restricted even though the flow or subflow continues to execute successfully. Flow Designer enforces a maximum limit on the number of script variables that can be defined within Script steps. This limit is governed by the system property: sn_flow_designer.max_script_variables Once the configured maximum number of script variables is reached, Flow Designer prevents the creation of any further script variables. This behavior is expected and designed to safeguard platform performance and stability. Note: Consider the performance impact raising the maximum number of script variables may have. For example, processing more script variables may risk the Script step running for more than an hour and being stopped by the default transaction quota rule.
