Happens every time regardless. Does anyone have any idea what's wrong?

So it looks like the error is that your messages.htm file was somehow missing the user (a.k.a. your name). If you open the file, you should look something like this:

    ...
    <div class="contents">
        <h1>Your Name</h1>
        <p><a href="../messages/....html">Friend A</a></p>
        <p><a href="../messages/....html">Friend B</a></p>
        <p><a href="../messages/....html">Friend C</a></p>
        <p><a href="../messages/....html">Friend D</a></p>
        <p><a href="../messages/....html">Friend E</a></p>
    ...

The line of interest is the one with the <h1> tag.

Do you see something different?

[ownaginatious]

Oh, I think I know the error. It seems you tried to parse one of the HTML files under messages/. You should be parsing the messages.htm file.

├── html/
│   ├── ...
│   ├── messages.htm <- Parse me!
├── messages/
│   ├── 1043...html
│   ├── ...

[miroslavtushev]

Oops, my bad

[miroslavtushev]

Ok, now I'm getting something different

Unable to locate the referenced chat file "/Users/miroslav/Downloads/facebook/html/sages/338103939874843.html". Please ensure that your "messages.htm" file is relative to your "messages/" directory in the following way while parsing:

    ├── html/
    │   ├── ...
    │   ├── messages.htm
    ├── messages/

Although if I open messages.htm via a browser and try to navigate to my messages - it works, no broken links.

[ownaginatious]

Hmm, I think I may have made some assumptions about how the messages.htm file is formatted that aren't always true. What do the <a> tags look like in your messages.htm file? Do they look like this?

<p><a href="../messages/<some long number>.html">Friend A</a></p>

Or like this?

<p><a href="messages/<some long number>.html">Friend A</a></p>

@ownaginatious

</h1><p><a href="messages/338103939874843.html">Friend A </a></p><p>

[ownaginatious]

Hmm, odd. I just downloaded my data again and it looks like Facebook broke the relative path...

Anyway, I fixed it to be compatible with that format and the old format (should they ever try to fix it...). Please try the latest version: 1.1.post6

[miroslavtushev]

sorry, still the same error...

[ownaginatious]

Did you do pip install --upgrade fbchat-archive-parser?

[miroslavtushev]

Yes. Does the code work for you?

[ownaginatious]

Can you post a stack trace?

[ownaginatious]

Yeah, it works for me. If you could post the error output, I could at least see which directory it's trying to look in :/

Not sure if that's the full stack, that's the only message I could get

[ownaginatious]

Well, only thing I can think of at this point is that the implementation of some of the Python os library functions work differently on your computer than mine. I tried switching to something that should be more reliable. Hopefully it'll work now: 1.1.post7

[miroslavtushev]

Works like a charm now, many many thanks to you for guiding me thru this process!!!

[ownaginatious]

Great, I'm glad that fixed it! :D

[eldenvo]

Hi there, I'm definitely using 1.1.post7 and I'm also getting the same thing:

[ownaginatious]

Which OS are you using?

[eldenvo]

Windows 10

[ownaginatious]

Hmm, it’s probably an issue with how the tool uses Python file system tools and Windows paths. This tool is unfortunately not well tested with Windows. I will look into it soon (gotta get a Windows VM running first).

[eldenvo]

No problem and thanks for your work - it has generally worked fine for me up until this change in structure!

[ownaginatious]

^ should be fixed now in 1.1.post8 👍
