Issue:
Error in Magento Migration Tool - Deprecated Functionality
When using the Magento Migration Tool, specifically version 2.4.5, for data migration, you may encounter the following error near the end of the data migration step:
In ErrorHandler.php line 62: Deprecated Functionality: substr(): Passing null to parameter #1 ($string) of type string is deprecated in vendor/magento/data-migration-tool/src/Migration/Handler/SetValue.php on line 35
This error occurs due to deprecated functionality in the code related to the use of the substr() function. However, there is a simple fix to address this issue.
Fix / Workaround:
To resolve this error, follow the steps outlined below:
- Open the file
vendor/magento/data-migration-tool/src/Migration/Handler/SetValue.php. - Replace the existing code around line 35:
$operator = substr($this->value, 0, 1); $value = substr($this->value, 1);
With the updated code:
$operator = ($this->value !== null && is_string($this->value)) ? substr($this->value, 0, 1) : null; $value = ($this->value !== null && is_string($this->value)) ? substr($this->value, 1) : null;
- Clear the Magento cache:
php bin/magento cache:clean
