A recent application I’ve deployed is occasionally throwing 500 responses (net::ERR_ABORTED) for assets (css and svg).
The application builds and deploys successfully, however it seems that serving the built assets occasionally fails for unknown reasons.
Additionally, site.webmanifest
will also occassionally return a 404.
For the javascript entry bundle, I get:
Refused to execute script from ‘https://www.nestingbird.co/assets/application.js’ because its MIME type (‘text/html’) is not executable, and strict MIME type checking is enabled.
Even though I’ve set type as text/javascript
.
