You could use conditional routes for that Adding and configuring routes – Latenode | Help Center

If you’re doing very simple filtering, you can use the filter block between nodes, but it’s not the most convenient option.

Recommended approach:
Create an intermediate JavaScript block that checks whether the number (from a variable) is in your ignore list.

The inside looks like this:

If the number is found in the list, it returns false.

Then just set the condition to check that the result is not equal to false:

This way, only the processes not in the ignore list will continue.

Example JavaScript code:

/** @CustomParams
{
  "input_value": {
    "title": "Input Value",
    "key": "input_value",
    "description": "The value to check",
    "type": "string"
  },
  "disallowed_values": {
    "title": "Disallowed Values (comma separated)",
    "key": "disallowed_values",
    "description": "List the values (comma separated) that are not allowed",
    "type": "string"
  }
}
*/
export default async function run({ data }) {
  const input = (data.input_value || '').trim();
  const disallowed = (data.disallowed_values || '')
    .split(',')
    .map(v => v.trim())
    .filter(v => v.length > 0);
    
  if (disallowed.includes(input)) {
    return { result: false };
  }
  return { result: true };
}

Let me know if you want to tweak the logic or make it dynamic with variables from earlier nodes.
