How to increase input variable count for action in flow designer

[deepikarama]

We have a requirement to add more than 20 inputs in a custom action. However, we are receiving the warning message:
"You have reached the maximum allowed input for this action."

We tried to increase the limit to 25, but the system property sn_flow_designer.max_action_vars is missing from the sys_properties table.

Hi @deepikarama ,

There is a quick workaround to your problem, You can create a JSON type flow variable and store all variable values corresponding to them and pass it to your action as single input and in your action you can parse that values corresponding to the keys in the json object. This makes development more maintainable than scrolling infinite in the mail flow.

If this helped you, please mark this as helpful.

Thanks,

Hi @deepikarama,

You can resolve this by creating the missing system property manually. These limits are controlled through system properties, and if a property is not present by default, it can simply be added. 

Please create a new system property with the following details: 

• Name: sn_flow_designer.max_action_vars 

• Value: Set this to the number of inputs you require (for example, 25). 

Once created, the updated limit will apply, and you should be able to add more inputs to your custom action.
 

For reference, a similar discussion can be found here: I can't find "sn_flow_designer.max_action_vars" and "sn_flow_designer.max_script_variables" .

Thanks & Regards,
