Registered and imported license succesfully, but license error banner still appears

Question

I started the Syncfusion free trial a few weeks ago and recently purchased Essential Studio Enterprise Edition Binary with TestStudio. I wanted to add my license key to my JavaScript project, so I followed the steps here to register a license key in Windows using an environment variable. I ran the npx syncfusion-license activate command from the terminal in Visual Studio Code, and there was a message telling me the license was imported successfully.

I ran npm start and opened up my web page, but still saw the banner with error message that it was built with a trial version. I looked at the troubleshooting page but that was not too helpful.

In my package.json dependencies I have:

"@syncfusion/ej2-base": "20.2.36"

I noticed if I remove the license variable and try activating the license it still says it was imported successfully.

Any ideas to troubleshoot what is going on?

Hi Derek,

Greetings from Syncfusion support,
 We have validated your reported
query along with your provided details, but we are unable to replicate any
issues. And we suspect that this issue might
raise due to duplicate packages in your project, we suggest you to remove the
duplicate packages. Kindly follow the below steps to remove the duplicate
packages and this issue will be resolved. For your convenience we have attached
the sample, please refer to the sample.1. Delete the
@Syncfusion folder from node_modules and the package-lock.json file from the
root folder.2. Update our
packages to the latest version (all packages should be upgraded to 20.*).3. Run the
‘’npm install” command to install the packages.We have introduced the license registration through npx
command in the volume 2 2022 release i.e.(v20.2.36). So if you are using the
packages below v20.2.36 then registering the license through the npx command
will not work. Please upgrade your packages to the latest version to avoid
these issue.Please find the below details to register the
license key using the npx command,        Register the license key with the environment
variable
 Set
     the environment variable as SYNCFUSION_LICENSE in the system
     and paste the license key as a value. It can be used in all applications
     on your machine.

Once
     set the SYNCFUSION_LICENSE environment variable, restart the IDE
     (e.g. Visual Studio Code) or application terminal (i.e. Command Prompt)
     before using the license activation command.

Open
     the command prompt in the application root directory and activate the
     license key by using the below command,

npx
  syncfusion-license activate

Once the Syncfusion license key
     is activated, the following console message will appear.
     License message:
     (INFO) Syncfusion License imported successfully.
