Can i work on this issue?

@Gaurav-Punjabi of course. And you don't need to ask for permission. Just be aware that point 1 is a duplicate of #26639 and the solution is discussed there.

Okay, got it👍.

which file do we need to look up for this issue ??i am a beginner please help a bit

@vbv2312 See #26639.

@Gaurav-Punjabi Are you still working on this?

@SharkyKZ thanks but with the help of discussions there i faced issues

1. i cannot replicate the issues on my system
2. i did not understand where was that particular code to be found
3. i don't know how to create a fix on the basis of the comments i got there because they had no end to it .the function joomla.submitform(task,document.getElementbyId()) was called in for all article,newsfeed and user then how come there are differences in the performance ?though i cannot replicate errror yet i am asking my assumptions .
   also can you list some good first bugs that a beginner can look upto to increase the involvement in open source .
   thanks

@vbv2312 sorry for late response. This fell off my radar.

1. Did you click Save and not Save & Close button?
2. Some of the files concerned are listed in the discussion here #26639 (comment).
3. Joomla.submitform() is executed but no validation is performed because button lacks form-validation attribute.

I was just having a look at the second part of this, which seems to still be an issue. So, from the initial description...

Steps to reproduce the issue

• create a newsfeed with an invalid link protocol such as blank://test

Expected result

• Info about incorrect scheme on save

Actual result

• message about invalid link but without the scheme information

Trying this out in in Joomla 4.0.0 beta5, I can recreate it ok I think.

So I guess it should be pulling in the string...
JLIB_FORM_VALIDATE_FIELD_URL_SCHEMA_MISSING="Invalid URL: URL schema is missing in %1$s. Please add one of the following at the beginning: %2$s."
...rather than the vanilla Invalid field: Link message.

I'll see if I can figure out what this is, the logic seems to be in libraries/src/Form/Rule/UrlRule.php and the form is, i think, defined in administrator/components/com_newsfeeds/forms/newsfeed.xml
