Dev.to API tool fails to check for changes before writing, risking data loss

By PulseAugur Editorial · [1 sources] ·

A tool designed to update articles on the Dev.to API was found to have a critical flaw where it would execute a write operation even if no fields were specified for modification. This meant that calling the `update_article` function with only an article ID could result in an empty update being applied, overwriting a live post with no record of the original content. Despite previous fixes aimed at improving logging and data validation, neither addressed the core issue of ensuring there was actually something to change before proceeding with the write operation.
