SPFx failed to load path dependency from component

Question

Why does my deployed SPFx webpart suddenly has an error? It works when I'm in the workbench, but the deployed one has this error. I followed this https://dev.office.com/sharepoint/docs/spfx/web-parts/get-started/deploy-web-part-to-cdn to create a simple webpart.

I think my farm has been upgraded to GA since the links in my network are all 2017-02-17.019

Answer 1

Make sure your gulp serve is running. We need to improve our error messages (working on it). This basically says "I can't load helloWorldStrings.js".

The easiest thing to do would be pop open your developer tools, and check for a 404 trying to load helloworldstrings.js. See what URL it is pointing to. If it is localhost:... it means your manifest is still pointing to your local copy, and you need gulp serve running in order to load them.
