I am getting the above error…
i don’t knw what the problem is…
And is there anything to do with netlify.toml file …if yes then what should be done with that file and how to create and where exactly because I have searched many times but not found any solution…
this is my github link where i have hosted the project…

(I have also changed the name of base directory as the name of the folder which contains the package.json file) and also what should be the name of publish directory? build or public??

Hi, @learner_Ankita, neither of the sites above exist anymore:

If you are still experiencing this issue, would you please send us a link to the deploy logs for the site at Netlify?

I was running into this error because I changed the base directory to something that didn’t exist. Hope that helps anyone who happens to find this page.
