Fixing 2 minor issues I encountered while following tutorial:

• Got an error when trying to use the format: 'email'. Removed this and it worked fine. Perhaps the real solution is to fix the ajv-format issue inside FoalTS? But this PR is enough let people proceed with the tutorial.
• Fixed minor spacing typo.

Issue

Running the command from the tutorial (foal run create-user email="john@foalts.org" password="john_password" name="John") generates a CLI error:

C:\workspaces\foal-react-tuto\backend-app>foal run create-user email="john@foalts.org" password="john_password" name="John"

Hi @RobK 👋

Thank you for reporting the issue!

This is indeed a regression introduced in v3.0.0 which uses version 8 of AJV. AJV v6 includes formats, v8 doesn't. Hence the error.

I opened a PR to fix this use. It will be released with v3.0.1.

Could you update the PR to revert back the change on the format? Then, we will be able to merge it to fix the import typo.

Thank you for having reporting this 👍 👍

Hi @LoicPoullain, I updated this PR to remove the format related changes and left in the other typo fix
