     The source map you are trying to load is in node_modules and not part of webpack bundle. "If not extracted and processed into the source map of the webpack bundle, browsers may misinterpret source map data" ref. When app is loaded that causes "ERR_UNKNOWN_URL_SCHEME" in chrome dev tools console.

     To process node_module source maps to webpack bundle, use source-map-loader loader. That will fix console warnings.

     Add dependency to package.json:

     "devDependencies": { "source-map-loader": "^1.0.0", ...} -

     Update webpack.config.js:

     module: { rules: [ { test: /\.m?js$/, enforce: 'pre', use: ['source-map-loader'], }, ],},-

     To generate source maps for snabbdom-test project in general you can use SourceMapDevToolPlugin.

     Update webpack.config.js:

     const { SourceMapDevToolPlugin } = require("webpack");-plugins: [ new SourceMapDevToolPlugin({ filename: "[file].map" }),...],-

   • 404 status code while making HTTP request via Python's "requests" library. However page is loading fine in browser

     Top Answer

     The website you mentioned is checking for "User-Agent"

     in the request's header. You can fake the "User-Agent" in your request by passing the dict object with Custom Headers in your requests.get(..) call. It'll make it look like it is coming from the actual browser and you'll receive the response.

     For example:

     >>> import requests>>> url = "https://www.transfermarkt.com/jumplist/startseite/wettbewerb/GB1">>> headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36'}# Make request with "User-Agent" Header>>> response = requests.get(url, headers=headers)>>> response.status_code200 # success response>>> response.text # will return the website content

   • 404 status code and its double meaning on a common-almost-restful api

     Top Answer

     Answered Oct 07, 2021 · 2 votes

     What about using 403 for the first case (together with the explanation) and 404 for the second? Since the RFC 403 refers to 404 as an alternative response code they might be related...

     403 Forbidden: The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead.

     403: You understand what the client wants but refuse to fulfill it. The client should not try again - it's forbidden until this resource is created - which you can explain as part of the answer.

     404: You know that the client wants something you won't provide and can tell him in good faith, that this resource will never exists.

     Update:

     RFC 2119 explains how the "SHOULD NOT" has to be interpreted:

     SHOULD NOT This phrase, or the phrase "NOT RECOMMENDED" mean that there may exist valid reasons in particular circumstances when the particular behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label.

     I think for your use case this is true. The client request shouldn't be repeated *without solving the reason stated in the 403 answer: "accessing this resource is forbidden because no user named mario exists". But if the client is sure that the reason went away, he is free to try again. But this might be only my interpretation of the 403 "should not be repeated" statement.

   • code : "ERR_BAD_REQUEST" Axios error: Request failed with status code 404

     Something in your URL is undefined, look at the request :

     GET http://localhost:3000/ undefined /api/products?populate=* 404 (Not Found)-

     It should not be undefined

     You can console.log the url near fetchDataFromApi's callsite to make sure it's the value that you expect.
