Nothing is listening on the host/port Python tried to connect to.

ImproperlyConfiguredPython

django.core.exceptions.ImproperlyConfigured: settings are not configured / SECRET_KEY must not be empty

Django can’t load its settings — DJANGO_SETTINGS_MODULE unset, a required setting missing, or an environment variable not provide…

AttributeErrorPython

AttributeError: 'X' object has no attribute 'y'

You accessed an attribute or method that doesn’t exist on that object type.

Django CSRFPython

Forbidden (403) CSRF verification failed. Request aborted.

Django rejected a POST because the CSRF token was missing, wrong, or the request origin isn’t trusted.

never awaitedPython

RuntimeWarning: coroutine 'fetch' was never awaited

An async function was called without await, so it never ran.

RuntimeError: Event loop is closed

Async code tried to use an event loop that has already been shut down.

Two steps away (21)

The server could not understand the request because its syntax, headers or body are malformed or invalid.

redirect_uri_mismatchAuthentication

OAuth Error: redirect_uri_mismatch

The redirect URI in your OAuth request doesn’t exactly match one registered for the client in the provider’s console.

divergent branchesGit

hint: You have divergent branches and need to specify how to reconcile them.

Git 2.27+ asks you to choose merge, rebase or fast-forward-only when local and remote both have new commits.

ECONNREFUSEDNode.js

Error: connect ECONNREFUSED 127.0.0.1:5432

Nothing is listening at that host:port — the target service is down or you’re connecting to the wrong address.

521Cloudflare

Cloudflare Error 521: Web Server Is Down

Cloudflare couldn’t connect to your origin — the connection was refused.

ETIMEDOUTAPI

API Request Timed Out (ETIMEDOUT / ReadTimeout / timeout of 30000ms exceeded)

The client gave up waiting — either for the connection to open or for the response to arrive.

gpg failed to signGit

error: gpg failed to sign the data — fatal: failed to write commit object

Commit signing is enabled but GPG couldn’t sign — no TTY for the passphrase, wrong key, or agent not running.

Django no such tablePython

django.db.utils.OperationalError: no such table: app_model

Django queried a table that hasn’t been created — migrations missing or not applied.

TemplateDoesNotExistPython

django.template.exceptions.TemplateDoesNotExist: app/page.html

Django searched all template directories and couldn’t find that template.

TypeError: not a functionJavaScript

TypeError: x is not a function

You called something as a function, but its value is not a function (it’s undefined, a string, an object…).

ImportErrorPython

ImportError: cannot import name 'x' from 'y'

The module was found, but the name you’re importing from it doesn’t exist — usually a version change or a circular import.

KeyErrorPython

KeyError: 'x'

You accessed a dictionary key that doesn’t exist.

403HTTP

HTTP 403 Forbidden

The server understood the request but refuses to authorize it — you (or the server process) are not allowed to access this resour…

Laravel: 419 Page Expired (CSRF token mismatch)

Laravel rejected a POST because the CSRF token was missing, expired or didn’t match the session.

Python not foundPython

Python was not found; run without arguments to install from the Microsoft Store

Windows ran the Microsoft Store “App execution alias” instead of a real Python installation.

UnhandledPromiseRejectionNode.js

Node.js: [UnhandledPromiseRejection] — This error originated either by throwing inside of an async function without a catch block

A promise rejected and nothing handled it; since Node 15 this crashes the process.

await outside asyncJavaScript

SyntaxError: await is only valid in async functions and the top level bodies of modules

await was used inside a function that isn’t async (or in a classic, non-module script).

AbortErrorJavaScript

AbortError: The user aborted a request. / signal is aborted without reason

A fetch was cancelled through an AbortController (or the browser cancelled it).

body already usedJavaScript

TypeError: Failed to execute 'json' on 'Response': body stream already read

A fetch Response body was consumed twice (e.g. calling .text() then .json()).

TypeError argumentsPython

TypeError: f() takes 1 positional argument but 2 were given

A function was called with more positional arguments than it accepts — very often a method missing `self`.

TypeError missing argPython

TypeError: f() missing 1 required positional argument: 'x'

A function was called without a required parameter.
