Thanks! I’ll get this fixed!

a couple more small issues in this chapter…

“add the following after // Configuire the rest of your application here”:
No such comment in the file as built from template.
I assumed this would be at the end of the file, and everything worked just fine.

‘vapor cloud run --env=production “revert --all --yes”’ aborts with message: “[CommandError.excessInput: Too many arguments or unsupported options were supplied: [”–env=production"]]".

Running the command without --env=production and manually specifying the production environment when prompted reverts the db as expected.


Glad I stumbled upon this, I was confuzzled with why it didn’t work.

Hmm thanks for letting me know! Looks like something has changed, will get that fixed for the next EA
