Blazor InputDate Error in FireFox

I use an InputDate control as:

                    <div class="form-group">
                        <label for="@("Birthdate" + usr.UsrId.ToString())">@L["lblBirhdate"]</label>
                        <InputDate @bind-Value=usr.PusrBirhdate class="form-control" id="@("Birthdate" + usr.UsrId.ToString())" @onkeypress="OnDateKeyPress" required/>
                        <ValidationMessage For="() => usr.PusrBirhdate" @Required="true" />
                    </div>

Describe the bug

A clear and concise description of what the bug is.

When I press the number: 0 in any date fields, it try to validate the date as in this example, the mouth as: 00

I get as soon as the keypress is done, an unhandled error exception as

System.InvalidOperationException: InvalidCharacterError: String contains an invalid character
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.InvokeRenderCompletedCallsAfterUpdateDisplayTask(Task updateDisplayTask, Int32[] updatedComponents)

To Reproduce

Insert an InputDate in a Blazor page, Open it in a Firefox browser. <InputDate class="form-control" id="Birthdate" required/>

Run it, insert a 00 for the month by typing only 0

Exceptions (if any)

System.InvalidOperationException: InvalidCharacterError: String contains an invalid character at Microsoft.AspNetCore.Components.RenderTree.Renderer.InvokeRenderCompletedCallsAfterUpdateDisplayTask(Task updateDisplayTask, Int32[] updatedComponents)

Further technical details

• ASP.NET Core version 3.1.3

Glad you tracked down the issue! Closing this now.

Finally, I found the problem, it was the damned @Required=“true” who fail with the FluentValidation… You can close it…
