After upgrading to bud 6.0 and following first path from the [Bud v6.0.0 released](https://discourse.roots.io/t/bud-v6-0-0-released/23359) whenever I am trying to use yarn build / dev the error comes up:

```

So escaping `$` in variable value should fix the issue:

Well thanks, it worked, but a new error comes in:

This has probably something to do with outdated packages.  
Try `npm outdated` and then update the `bud`-related packages, one by one.

Well everything is up to date :frowning:

So, i’ve found the issue.  
Everything is working when i delete salt keys from the .env file.  
So basically i’ve generated new ones and everything is working. Keys were generated via [WordPress Salts](https://roots.io/salts.html).

These are the faulty ones:

```
AUTH_KEY='N$d<475]Syb6/|DSA&q7z2l;Li@[hfJx)o?riz-X&s<xXz$7!]?H8nxCDQtwn^RE'
SECURE_AUTH_KEY='#x*B^Vlppd.<`t4IciZ$$UejKC`uB7s;aO$6FC2`jg]^e(|v=CH+]Rk(J2?,OaZg'
LOGGED_IN_KEY='nP$^4oL-%}Ia*l3z9{ki]1QXqW{Cy99{.94(o+0EZMMhAFtPb0H|#T8*`I,Cs0/_'
NONCE_KEY='jZ5;l`RilJM+X)@Ww[hx|MWRX_JCkz4>SiN@BCQppaOR_+QV&|^H`ya4z6}qO.32'
AUTH_SALT='I{gr5LCTf&=j}tjb[d7>q(:fR2RY>`,z7u[A*N;30`[[35>W]wE]g)cSw,1Ww,z9'
SECURE_AUTH_SALT='AzCIP/R`T#&4-Oz<V46L@X@Xqnv+VhDNbt+YuUmeicq,^Mhk9Tthg2>W9RPJ(m`?'
LOGGED_IN_SALT='?wsA|k20xv!VY4KvBk0B{U&F!}IRzxp>r--^F|9(t3vKFWt<`+pnL6{2d6HJmqPS'
NONCE_SALT='$=et66]kTt(+($c:mIRW1oh+B=E[gCQXFJr<VO+8J=a)*?,kOL;?^.5xac41%9pH'
```

I think it’s the kind of issue @ben should look into and investigate further :slight_smile:

It seems like bud was tripping up on your dotenv. it shouldn’t fail like that.

were the old values quoted? if they weren’t and they contained regexp-like characters, dotenv-expand might have choked on them.

This is because of an unescaped `$` being interpolated by bud as variable expansion.

I was able to reproduce the issue exactly and [write tests around it](https://github.com/roots/bud/blob/6e3996721b34a8b1588bcc5c069f3b20b3661d9d/tests/unit/bud/context/env.test.ts). Thanks for bringing it up @fakenso.

The next release of bud will not try to interpolate environment variables that are not sourced from `[projectRoot]/.env`. You will still need to escape `$` in theme .env file but otherwise this shouldn’t be such a mystery in the future.
