@semklim Hi, I used your commit to make it work, but get error in vercel logs. Not sure what's wrong here

I going to check localy your problem, but please check your .env file. I think you forgot to add the variable(s).

Here’s my .env file that worked on Vercel:

@semklim thank you!

@m0sviatoslav, I also found where the problem was. Problem with the vercel Sensitive flag. I am going to correct the readme.
