Java OpenApi format date

[danosavraam]

Hello, I am using OpenApi in my Java project. In my yaml file I used type string and format date. But I am facing one issue with the year.
My request should come like this 2022-01-30 if I give wrong day or month validation is working and I am getting error message but for the year this is not happening. For example if I sent wrong year like this 20223131-01-30 I am not getting error message that year has to be 4 digits or there is no such year. How can I fix this?

Thank you.

20223131 is a valid year, albeit not very likely to be the correct value in your application.

You could add an extra check like "maxLength": 10" or "pattern": "^\d{4}-\d{2}-\d{2}$" to ensure that you get four-digit years.

Closing as answered - if that pattern does not work, then it is a tooling issue and should be raised with the tooling vendor. Note that support for format in validation is technically optional, so you need to consult your tooling documentation to determine if it is supported. If not, the pattern given is the typical workaround.
