[DevLink Bug] Build Failure in Next.js: fonts.manifest.json mismatch in v1.14.0+

Webflow Cloud

Hi Webflow Team,

I'm reporting a regression in the latest versions of @webflow/webflow-cli (v1.14.0 and potentially the new v1.19.0).

After running a webflow devlink sync, our Next.js project fails to build with the following error: Module not found: Can't resolve './webflow_modules/fonts.manifest.json'

The Root Cause: It appears there is a file extension mismatch in the auto-generated files:

  1. The generated DevLinkProvider.js contains an import pointing to a JSON file: import fontsManifest from "./webflow_modules/fonts.manifest.json";

  2. However, the CLI actually generates a JavaScript file in that folder: webflow_modules/fonts.manifest.js

Because the import explicitly specifies .json, the build system (Webpack/Next.js) cannot find the module.

Steps to Reproduce:

  1. Use @webflow/webflow-cli v1.14.0 or later.

  2. Run webflow devlink sync on a project (even one using only Google Fonts).

  3. The sync produces a .js manifest but the provider code expects a .json manifest.

Environment:

  • Node.js v20+

  • Next.js 15

  • @webflow/webflow-cli 1.14.0+

Is this a known issue with the transition to the new "DevLink Export" workflow? For now, we've had to downgrade to v1.13.1 to maintain stability.
