🐛 BUG: Unable to use D1 locally

What version of Wrangler are you using?

2.2.1

What operating system are you using?

Mac

Describe the Bug

TEST_DB database is undefined instead of BetaDatabase {} upon checking the context.env.

npx wrangler@2.2.1 pages dev ./public --d1=TEST_DB --local-protocol https --local --persist --log-level debug

console.log(env) { ASSETS: Fetcher {}, TEST_DB: undefined }

npx wrangler@2.2.0 pages dev ./public --d1=TEST_DB --local-protocol https --local --persist --log-level debug

console.log(env) { ASSETS: Fetcher {}, TEST_DB: BetaDatabase {} }

Creation of the database is okay ./wrangler/state/d1/TEST_DB.sqlite3 but the only problem is the binding.

This appears to be a bug in wrangler meaning the --d1 flag doesn’t work correctly.

It looks like you can only add D1 bindings in wrangler.toml. So to fix this right now you can add the following code to your wrangler.toml (obviously replacing the values that are relevant for your DB)

[[ d1_databases ]]
binding = "MY_DATABASE"
database_name = "my_database"
database_id = "azertyazerty"

You also then need to REMOVE the --d1 flag you’re passing to wrangler pages dev and also add the --persist flag`.

However this is apparently a temporary workaround as wrangler.toml isn’t supposed to work with cloudlfare pages.
