Migrate Magento 1.9.4.4 to 2.4.x error (migration tool)

[josecamposefd7]

Hi. I'm trying to migrate content and settings from magento 1.9.4.4 to 2.4.5 and I'm getting the following error:

[2023-01-05T10:36:48.188095+00:00][INFO][mode: data][stage: data migration][step: Tier Price Step]: started
0% [>---------------------------] Remaining Time: < 1 sec
In ErrorHandler.php line 62:

Deprecated Functionality: substr(): Passing null to parameter #1 ($string) of type string is deprecated in /opt/magento/vendor/magento/
data-migration-tool/src/Migration/Handler/SetValue.php on line 35

has anyone seen this before?

best regards

Jose

We have the same issue, appears to be a php 8.1 issue with the data migration.

Did you get around this? try to see if using php7.4 will work just for the migration.

1.9.2.1 to 2.4.5

Replace src/Migration/Handler/SetValue.php with https://github.com/magento/data-migration-tool/blob/2.4-develop/src/Migration/Handler/SetValue.php and re-run migration, (fixed issue for us)
