key/value cannot be null or undefined. Are you trying to inject/register something that doesn't exist with DI?

Error message

key/value cannot be null or undefined. Are you trying to inject/register something that doesn't exist with DI?

Error explanation

This error occurs when a null or undefined key is used in a DI container operation, such as container.get(key) or container.register(key, ...). Dependency Injection keys must always be defined and valid.

Common causes

• A circular dependency or bundler issue (e.g., Webpack) results in a key being undefined at runtime.

• A typo or incorrect import leads to a missing or undefined key.

• Attempting to register or resolve a dependency before it is defined.

• Plugins or libraries that incorrectly provide a null/undefined key.

How to fix

• Ensure all keys used in DI registration and resolution are defined and not null/undefined.

• Check for circular dependencies in your module graph, especially with bundlers.

• Double-check imports and the order of registration.

• If using plugins, ensure they are not introducing null/undefined keys.

Debugging tips

• Check the stack trace to see where the null/undefined key was used.

• Search your codebase for all registrations and resolutions of the key in question.

• If using a bundler, look for circular dependencies or import issues.

• If using plugins, try disabling them one at a time to isolate the source.
