Unreadable Sentry Errors

I am just new to using sentry as a means of error tracing. I have already uploaded sourcemaps, but I am still getting unreadable errors. I have been searching about it but still cannot find the reason why it is not working.

I am using nuxtjs with vuejs. I testing it from my localhost.

this is how I see the errors

* `webpack-internal:///./node_modules/axios/lib/core/createError.js` in `createError` at line `16:15`

* `webpack-internal:///./node_modules/axios/lib/core/settle.js` in `settle` at line `17:12`

* `webpack-internal:///./node_modules/axios/lib/adapters/xhr.js` in `XMLHttpRequest.handleLoad` at line `69:7`

this is my sourcefiles

I don’t know what am I missing here.
