refs on function componentsReact

Warning: Function components cannot be given refs. Attempts to access this ref will fail. Did you mean to use React.forwardRef()?

A ref was passed to a function component that doesn’t forward it.

Property was accessed during render but is not definedVue

Vue: [Vue warn]: Property "x" was accessed during render but is not defined on instance

The template references a variable/function that the component doesn’t expose.

Avoid mutating a prop directlyVue

Vue: [Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders

A child component assigned to a prop. Props flow one way — the parent owns the value.

Two steps away (8)

uncontrolled to controlledReact

Warning: A component is changing an uncontrolled input to be controlled

An input’s `value` started as `undefined` (uncontrolled) and later became a defined value (controlled), or vice versa.

cannot lock refGit

error: cannot lock ref 'refs/remotes/origin/x': is at … but expected … / unable to update local ref

Git couldn’t update a reference — stale remote-tracking refs, case-only branch name clashes, or a leftover lock file.

broken refGit

warning: ignoring broken ref refs/remotes/origin/HEAD

A ref file is empty or points to a missing object — usually refs/remotes/origin/HEAD after the default branch changed.

ReferenceErrorJavaScript

ReferenceError: x is not defined

Code refers to a variable or function name that doesn’t exist in the current scope.

TemplateDoesNotExistPython

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

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

NG8002Angular

Angular: NG8002: Can't bind to 'ngModel' since it isn't a known property of 'input'

The template uses a property binding that no imported directive provides — for ngModel, FormsModule isn’t imported.

non-boolean attributeReact

Warning: Received `true` for a non-boolean attribute `x`.

A boolean was passed to a DOM attribute that expects a string, or a custom prop leaked through to a DOM element.

key is not a propReact

Warning: `key` is not a prop. Trying to access it will result in `undefined` being returned.

A component tried to read props.key, which React reserves and never passes down.
