Unbelievable that this is still an issue. You can apply this patch to fix it:

mlaurense, Already tried to apply your patch, but its the same issue for 2.4.5 version. Any thoughts? This is not yet fixed...

Thank you

@VrumVrum You mean it is STILL not fixed... it appears the file is the same in 2.4.5 tag, so you should be able to apply the patch successfully. Check if your vendor/magento/data-migration-tool/src/Migration/Handler/TruncateSuffix.php is changed; line 93 should contain the if ($value !== null)
