@description
|
||
|
|
A required input was accessed but no value was bound.
|
||
|
|
|
||
|
|
This can happen when a required input is accessed too early in your directive or component.
|
||
|
|
This is commonly happening when the input is read as part of class construction.
|
||
|
|
|
||
|
|
Inputs are guaranteed to be available in the `ngOnInit` lifecycle hook and afterwards.
|
||
|
|
|
||
|
|
## Fixing the error
|
||
|
|
|
||
|
|
Access the required input in reactive contexts.
|
||
|
|
For example, in the template itself, inside a `computed`, or inside an effect.
|
||
|
|
|
||
|
|
Alternatively, access the input inside the `ngOnInit` lifecycle hook, or later.
