You are trying to SCRAPE POSTS
But your last search step returns PROFILES (notes returns profile). As is shown by the warning.
Then you change the scrape to a saved scrape where your FIRST STEP IS "NOTES OF POST"
But your search input IS A PROFILE URL.
You are telling the program to SCRAPE NOTES FROM POST from <profile_url>
But a profile page does NOT have notes. The program is expecting a POST_URL and you are entering a PROFILE_URL.
Perform the search I have detailed above in the SEARCH USERS function and it works.
Also please provide the requested information. Logs / screenshots are much easier to work with than videos as I don't really need to see you switching from app to browser to read the instructions
