.env file in pipenv (django) - ValueError: embedded null character

Question

I got a .env file inside my project

SECRET_KEY="vvvvvvvtestvvvvv"

I run pipenv shell

But I get like a bunch of errors.

PS S:\github\fozvi> pipenv shell
Loading .env environment variables…

What am I doing wrong?

If you change your secret key does the problem continue? – WombatPM Jan 24 '19 at 15:42 — WombatPM, Jan 24 '19 at 15:42

Just ran into this problem. It may be a file encoding issue.

Try opening the .env file in Notepad++, change the encoding to UTF-8, then save the file and try again.

Can easily see and change it in VSCode bottom right. just click it and select save with encoding. Mine was UTF16FE for some reason – BrinkDaDrink Sep 02 '20 at 20:15

Probably your SECRET_KEY contains a \0 somewhere and you can't have NUL bytes in an environment variable. Just remove it from your SECRET_KEY in the env file and it should work.
