The path xxx.car is not whitelisted in pathfilter CF2021 update 23

You can whitelist the CAR file in the configuration file C:\ColdFusion2021\cfusion\lib\pathfilter.json, as follows:

1. Open pathfilter.json in an editor. The relevant settings you need are

    "car": {
           "deploypath": "C:/full/path/to/yourFile.car",
           "associatedfiles": ""
       }

    

2. If there are any files or directories associated with the CAR file, then you should include their full paths as the values of “associatedfiles”, using a comma to separate the different paths,
