[BUG] Improve error message "org-back-to-heading: Before first headline at position 1" [9.6.8 (release_9.6.8-3-g21171d @/usr/local/share/emacs/29.1.50/lisp/org/)]

[BUG] Improve error message "org-back-to-heading: Before first headline at position 1" [9.6.8 (release_9.6.8-3-g21171d @/usr/local/share/emacs/29.1.50/lisp/org/)]

[c.buhtz]

Hello,

using the first time this Emacs in build bug report thing. But have to 
send the mail via copy & paste because the bug reporter didn't work out 
of the box.
The "From" field is not valid. Modified it manually in the buffer. But 
didn't work.
Emacs tried to use STARTTLS with posteo.de:25 which is wrong I think. 
Should be port 587 but don't know how to set this.

OK, now the real problem:

This is not a support question about how to solve a problem or the error
message I do report here. It is a request to improve that error message
to help users understand the real problem and find a solution by their
own.

I get the this error message in context when using the Org attachments
feature (C-c C-a plus c).

     "org-back-to-heading: Before first headline at position 1 in 
buffer..."

I have no idea about the brackground here. And I also not a regular user
of orgs attachment feature. So I can not provide a better error
message. This will be up to you. Thank you.

Kind

I believe that this problem have been fixed on main.
If not, please provide more details on how to trigger the error.

Something is off in your email settings (in emacs or in system mailer).

Dear Ihor,
thanks for reply.

Do you mean the message was improved or the message do not appear 
anymore? Can you link please to the sources file where I can see the 
message. Let's see if I understand it. :D

> If not, please provide more details on how to trigger the error.

That is the simple example:

     :PROPERTIES:
     :ID:       a7f2b708-d2f9-41d5-a263-d82540b10b23
     :END:
     #+title: test2
     #+date: [2024-03-10 16:42]
     Paragraph

After writing my first message I learned that there need to be a heading 
that files are attached, too. I don't understand why. So I assume the 
reason for the error message was that there is no heading in that org 
file?
But I would strongly disagree. An org file has a heading by definition 
even if it is empty. The heading string (#+title) might not exist and is 
empty but there is always an ":ID:". To my very(!) limited knowledge I 
would treat this behavior also as a bug. But there might be a good 
reason for this behavior.

> Something is off in your email settings (in emacs or in system mailer).

I use Thunderbird. There are no other email settings. Never used Emacs 
with mails. I always wonder why debian-bugreport is able to send mails. 
:D
But copy & paste is good workaround in the first please.

The error message should not appear anymore when you try to attach a
file before first heading.

Are you saying that the above example will trigger an error on the
latest main when you try to attach a file?

Ok.
Since I cannot reproduce the problem on the latest main, but can on
bugfix, I am canceling this bug as it is fixed on main.
Canceled.

> Is there a stable version with this bug fixed?

No. It is only fixed on main.
