It seems you're encountering an error when trying to remove a lead from a Smartlead campaign. To help resolve this, let's first ensure you're using the correct Lead ID. Here's what you can do: 1. Use the "Lookup Lead in Campaign" action first to get the correct Lead ID. 2. Make sure the Lead ID you're using is a valid integer, not "NaN" (Not a Number). 3. Double-check that you're inputting the Lead ID correctly in the "Remove Lead from Campaign" action. If you're still encountering the error, could you please copy and paste the full JSON response you're receiving? This will help us troubleshoot further.

The "NaN" error suggests the Lead ID isn't being recognized as a valid integer. To fix this: 1. Ensure you're using the correct Lead ID from the "Lookup Lead in Campaign" action. 2. Verify the Lead ID is a valid integer, not "NaN" or empty. 3. Double-check you're inputting the Lead ID correctly in the "Remove Lead from Campaign" action. If the issue persists, please copy and paste the full JSON response you're receiving so we can troubleshoot further.

in the lookup output, it’s adding “Found” at the end of the email which is probably changing the lead id or campaign id to not being an integer
