Upgrade status module throws this warning Call to deprecated method getContent() of class League\Csv\AbstractCsv in csv_serialization/src/Encoder/CsvEncoder.php.
It looks like the getContent() function of League\Csv\AbstractCsv class will be removed in next major release. And the way csv_serialization requires league/csv in composer.json, Anyone requiring the csv_serialization module will automatically fetch the major release of league/csv and thereby could get affected with these deprecations.
Temporary solution: We could lock the league/csv to 9.7.1 in composer.json and create a release to be safe from the errors.
: Well, It will be to review the deprecations and use proper code from new release of league/csv
