Wrangler 2 routes property ([mf:err] TypeError: Invalid URL)

With wrangler 2 the route property is like;

route = { pattern = "https://example.com/*", zone_id = "<ignored>"}

thus this following line fails with like http://[object Object];

It’s for mounts (https://miniflare.dev/core/mount). If you have multiple workers in the same Miniflare instance, Miniflare uses the routes for selecting the correct worker. You’re right this could be lazy, and not used if workers aren’t mounted.

Thanks for reporting this. A temporary solution to this might be to create a separate wrangler.toml file for Miniflare, then point Miniflare to that using the --wrangler-config/-c flag.

Of note, Wrangler 2 includes some things like automatic esbuild bundling and pages functions support that I don’t think will ever be added to Miniflare directly.
