create-t3-app help : something weird with .env

I followed along with the T3 Stack Tutorial - FROM 0 TO PROD FOR $0 video. I have watched these steps in the video 4 times now to make sure I've followed them correctly. My .env is set up. The DATABASE_URL is added into Vercel as an Environment Variable. I changed schema.prisma. My .env looks like the below. It runs with npm run dev.

PLANETSCALE_PRISMA_UN=blahblahblfklsdfklsdf
PLANETSCALE_PRISMA_PW=pscale_pw_asdfasdfasdfasdfasdfasdf
DATABASE_URL=mysql://asdfasdfasdfasdfasdfasfasdf:pscale_pw_asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf@aws.connect.psdb.cloud/sdfsfsdfdfs?sslaccept=strict

Vercel error:

Turned out it was because I enabled NextAppRouter. Once disabled, everything worked.

I have the same error, could you tell me how you disabled NextAppRouter please.

MikitzOP•11mo ago

I did not disable it. Instead, I just initialized a brand new project with npm create t3-app@latest and made sure to not use NextAppRouter
