Converting a drupal/drupal site to Work With Composer

At our company we have several sites that appear to have been made using the now deprecated method of composer create-project drupal/drupal. We’ve been fine using previously documented methods to remove the replace block in composer.json and move the drupal/core require statement to update drupal/core.

However, I’m now running into a strange issue with a very specific Contributed Module that is detecting the `”name”: “drupal/drupal” statement and version as 1.0, which then conflicts with dependencies it wants to install. I tried removing the name field since composer docs state it is only required for published packages, but this does not help resolve it.

Some other google results suggest that my drupal core is missing a .git repo that may be required to detect versions? How would I resolve this if it’s the case? What else can I try?

Error, caused by composer require drupal/csv_serialization:
