What steps can be taken to address the InvalidPipeArgument error when working with dates?

When attempting to format a date in a specific way using the pipe date, I encountered an error:

Uncaught Error: InvalidPipeArgument: 'Unable to convert "25/01/2019" into a date' for pipe 'e'
    at Xe (main.fc4242d58c261cf678ad.js:1)

    at $a (main.fc4242d58c261cf678ad.js:1)
    at us (main.fc4242d58c261cf678ad.js:1)

The date information was retrieved from the API as a string with the value of "25/01/2019," and I attempted to display it in HTML using the following code:

{{ item.date | date: 'dd MMM yyyy' }}

I am unsure if I have made an error. My intention is to present the date in a different format, considering that the input date is a string type.

Is there a solution for this issue? If so, how can I achieve my goal in this scenario? Your help is greatly appreciated.

Please note: This error did not occur on my local machine. It only surfaced when I deployed my web application to a real environment.

Answer №1

The documentation explains

A valid date expression can be a Date object, a number (representing milliseconds since UTC epoch), or an ISO string format

Remember that 25/01/2019 is not in ISO string format, but 2019-01-25 is. Note: there are alternative date pipes available outside the angular common package or you have the option to create your own.

Answer №2

Expanding on the response by @David Palita,

Start by converting the data type from String to Date, then utilize the DatePipe functionality as previously suggested,

item.date = parseDate(item.date, 'dd/mm/YYYY');

If you encounter any challenges on stackblitz, feel free to provide more details for tailored assistance.

For additional insights, I suggest referring to this Stack Overflow inquiry.
