Each time I attempt to utilize the JSON pipe to pass my data, an error message appears in the console:
Unhandled Promise rejection: Template parse errors:
The pipe 'json' could not be found (...
Can someone help me understand what mistake I am making?
It's possible that you overlooked the need to import CommonModule:
import { CommonModule } from '@angular/common';
@NgModule({
...
imports: [ CommonModule ]
...
})
Make sure to follow the instructions provided in the comments, especially when utilizing the json pipe.
My situation involved the addition of the CommonModule, however, the component was not included in the declaration of any module
(I was dynamically creating the component using ContainerRef)
Make sure your parent Module of the component follows this structure.
import {NgModule} from '@angular/core';
import {AuditTrailFilterComponent} from './components/audit-trail-filter/audit-trail-filter.component';
import {CommonModule} from '@angular/common'; <-- Ensure not to miss this part !!!!
@NgModule({
imports: [
CommonModule, <-- Don't forget this step !!!!
],
declarations: [AuditTrailFilterComponent],
exports: [
AuditTrailFilterComponent
]
})
export class AuditTrailModule {
}
In my case,
I found that I needed to include it within the providers section of the app.module.ts file
@NgModule({
providers: [
{ provide: JsonPipe }, <-- Don't forget this step !!!!!
This issue may arise when defining your component within a Lazy-loaded module and attempting to include the component in a route that has not triggered the loading of that module.
For example, I recently encountered this problem with the following code:
children: [
{
path: 'editor',
loadChildren: () => from(import(/* webpackChunkName: "editor" */ '../editor/editor.module').then(m => m.EditorModule))
},
{
path: 'multi-preview',
component: MultiPreviewerComponent // defined in Editor.module (lazy-loaded)
}
]
