Finding: In the reporter's account, a cloudflare.config.ts Worker whose Durable Object binding names the Worker itself fails under @cloudflare/vitest-plugin with experimental newConfig, and the reporter offers a miniflare.durableObjects override as a workaround, but the issue shows no success result for it. Source: https://github.com/cloudflare/workers-sdk/issues/16012 (open in the supplied material; maintainer status unknown). Not verified by KFA. Reporter claim: The reporter attributes the failure to convertToWranglerConfig() emitting script_name for a self-reference. This root cause is the reporter's analysis, not maintainer-confirmed. The reporter also describes a second symptom, a cf dev container error for a container attached to a self-bound Durable Object. Bot reproduction (separate claim): An automated triage comment on the same issue (https://github.com/cloudflare/workers-sdk/issues/16012) is LLM-generated. It reports reproducing symptom 1 only. Its archive link is stated to require Cloudflare Access, so the archive was not inspected. The supplied comments report no workaround test and no reproduction of the cf dev container symptom. Workaround as offered by the reporter: override the binding in the plugin's miniflare option: cloudflareTest({ experimental: { newConfig: true }, miniflare: { durableObjects: { MY_DO: { className: "MyDurableObject", useSQLite: true } } } }). The issue shows this code but no test output, and does not state that it resolves the failure. In the reporter's example the class is declared with storage: "sqlite" and the override sets useSQLite: true; no wider rule is stated. Status: This is a reporter-offered workaround only. It is not a confirmed fix or a released fix, and KFA has not tested it. No third-party report of testing it appears in the supplied comments, which may omit middle comments. Whether it applies to the cf dev container symptom is unknown. The report says its reproduction is in a linked PR with an integration test; that PR's content and status were not supplied, and no fix commit or release is supplied.

Proposed approach

Problem id
904f3991-b5e0-4dbc-8344-20f47ca467d7
Proposed action
Source-backed, not verified by KFA: the reporter offers a miniflare.durableObjects override in cloudflareTest options mapping the binding name to className MyDurableObject with useSQLite true. No success result is shown in the source. In the reporter's example the class is declared with storage sqlite.

The reporter's bug environment: @cloudflare/vitest-plugin 1.3.4 and 1.3.5, wrangler 4.146.0, cf CLI 1.0.0-beta.10, @cloudflare/config 0.22.0; Node 26.7, macOS 26. These versions describe the bug; no workaround test result is shown in any environment. Other environments unknown.
Limitations

Text
External report; KFA did not reproduce. The automated reproduction is an LLM-generated bot summary of the original bug; it reports no workaround test, and its archive requires Cloudflare Access so it was not inspected. The cf dev container symptom was not reproduced by the bot. Root cause is the reporter's analysis; maintainer status unknown. No workaround success result is shown, and no third-party test report appears in the supplied comments, which may omit middle comments. Applicability to the cf dev container symptom is unknown. No fix commit or release is supplied. The report references a linked PR with an integration test; its content and status were not supplied. The unrelated promotional link in a third-party comment was ignored.
