In this SharePoint framework article, I will discuss a SharePoint Framework error as:  “[spfx-serve] The api entry could not be loaded: node_modules/@microsoft/sp-webpart-workbench/lib/api/ “.

So while I was working on SharePoint Framework to build a web part for SharePoint modern sites, I was executing the command as “gulp serve” in the SharePoint 2016 Management Shell.  After a while, It throws an error as “[spfx-serve] The api entry could not be loaded: node_modules/@microsoft/sp-webpart-workbench/lib/api/ “. You can see that SharePoint Framework error in the below screenshot.
