Hi there, thank you for taking your time to create your first issue. Please give us a bit of time to review it.

I think it's that simple that the fix you are referring to here #1012 isn't released yet.

Can you please test with dev-main branch?

[MarCsharpElo]

Thank you tomasnorre for your immediate reply.

Before I initiated this ticket I had copied the two code lines from ticket 1014 into the file "Classes/Middleware/FrontendUserAuthenticator.php" on my typo3 instance

add line 130 $frontendUser->user[$frontendUser->userid_column] = 0;
add line 131 $frontendUser->user[$frontendUser->username_column] = '';

Despite of that the described error occurred. Now I am not sure, if I must do more actions to prevent the error.

Unfortunately I have no idea to find out how I can use the code in the main branch.

Please could you be so kind to tell me, what files I must transfer to my typo3 instance or which further manually code changes I have to do in order to complete the fix.

Best greetings

You can make a git clone of the main branch, and upload all. I'm currently not working, so cannot help you further, sorry.

I made a git clone and transferred it to my development environment. This was how I installed the main branch:

• Unzip the zipfile in the crawler extension directory with winscp
• delete one slash in the file ext_localconf.php to avoid a 503 error in the path name
• add the directory "vendor" in the directory "/html/typo3/typo3conf/ext/crawler/Resources/Private/Php/Libraries"; the source was my backup directory with the previous installed extension
• flush typo3 and PHP caches

To test the installation I ran the crawler by starting the scheduler job manually. The two logfile messages occurred again (undefined array key "username" and "uid") in a great number.

For the second test I deleted the VAR-directory.

Maybe there is still a library missing for the buxfix because I don't use composer? I understand that you can't reply immediately. That doesn't matter. Thank you.

I have just released a version 11.0.8 of the TYPO3 Crawler which should contain the fixes from above. I'll close the issue for now. Please let me know if not fixed in the newest release.
