cloudflare-wrangler-platform-worker-do-issue

Example repository for issue deploying update to Cloudflare Platform Worker with Durable Object migrations.

Reproduction steps

1. Create a Platform Worker by deploying into an existing dispatch namespace:

   yarn wrangler deploy --dispatch-namespace REDACTED

2. Observe the Platform Worker deploys successfully:

   % yarn wrangler deploy --dispatch-namespace REDACTED
   yarn run v1.22.19
   $ /wrangler-error-do-mig/node_modules/.bin/wrangler deploy --dispatch-namespace REDACTED
   
   ⛅️ wrangler 3.80.4
   -------------------
   
   Total Upload: 0.67 KiB / gzip: 0.37 KiB
   Your worker has access to the following bindings:
   - Durable Objects:
      - EXAMPLE_DURABLE_OBJECT: ExampleDurableObject
   Uploaded example-script-name (4.35 sec)
   Dispatch Namespace: REDACTED
   Current Version ID: a0871c1d-cd06-4082-bbb7-208c995ce8fc
   ✨  Done in 4.99s.

3. Update the Platform worker by deploying again:

   yarn wrangler deploy --dispatch-namespace REDACTED

4. Observe the Platform Worker fails to deploy:

   % yarn wrangler deploy --dispatch-namespace REDACTED
   yarn run v1.22.19
   $ /wrangler-error-do-mig/node_modules/.bin/wrangler deploy --dispatch-namespace REDACTED
   
   ⛅️ wrangler 3.80.4

   Total Upload: 0.67 KiB / gzip: 0.37 KiB
   Your worker has access to the following bindings:
   - Durable Objects:
