Angular - the provided Date input does not match the expected format

To change the format of a date to dd/MM/yyyy, I have created a custom pipe as shown below:

import { Pipe, PipeTransform } from '@angular/core';
import { DatePipe } from '@angular/common';

@Pipe({
    name: 'dateFormat',
})
export class DateFormat implements PipeTransform {
    transform(value: string) {
        var datePipe = new DatePipe("fr-FR");
        return datePipe.transform(value, 'dd/MM/yyyy');
    }
}

When I use this pipe in my code like this:

this.editOrganizationForm.patchValue({
    startDate: this.dateFormat.transform(organization.effectiveDate.startDate);
})

I encounter the following issue:

The specified value "02/05/1999" does not match the expected format, which is "yyyy-MM-dd".

Answer №1

The specified value of "02/05/1999" does not match the required format of "yyyy-MM-dd".

You are being asked to provide the date in the 'dd/MM/yyyy' format.

Try returning the transformed value using datePipe.transform(value, 'dd/MM/yyyy');

Have you considered using:

return datePipe.transform(value, 'yyyy-MM-dd');
