Hi @payingattention, your feedback and experience is important is remedying the issue you are experiencing. I have yet to isolate the part of the WARC that WARCreate is creating that is causing Webrecorder to choke. It is the responsibility of WARCreate to generate valid WARCs and not the expectation of other tools to account for any violations of the spec.

While I hope Webrecorder will improve to make the processing of invalid WARCs (ping @ikreymer) still usable in their tool suite (as there might be other tools with a similar affliction as WARCreate), I will need to isolate exactly what sort of record or formatting issue is causing the issue of tools meant to make the files WARCreate generates usable.

I do not have the time to do this at the moment (WARCreate is currently a volunteer-run, unfunded project), but am committed to get it back to a working state with time. Further independent contributions or studies onto the reasons for the effects you described (and of course, PRs) are welcomed.

Also, @payingattention, if you would be willing to provide the resultant WARC, this can be used as the basis for reproducibility.

Thank you, the greater spec/format is drastic improvement over just trusting archive.org/webcitation.org/archive.today for user-centric evidence gathering and giving users proof, we are fortunate to be the first to know the toolability exists, so troubleshooting WARCs is actually important for me:

• 20200704064631467.warc.zip is exact same archive from screenshot given.
• 20200708172743178.warc.zip is the same site but tried again fresh today, sadly same error.

While I have limited forensics as a user, I gather by my Ubuntu Linux system's U.I. behavior, that it's not showing the official WARC mime-type thumbnail (other .warc's show a package thumb/icon) because the generated archive copy itself is not saving completely/fully, if I'm forced to guess.

I appreciate the .warc still shows basic metadata for reference in a human-readable format. Thank you for the free open source extension, I hope my WARC zips help reproduce the error, I value your time.
