Hi Paul,
Greetings from Syncfusion support.
We have prepared a simple gantt sample using nextjs and
registered your license key generated for version (v20.3.47) in the
application. but were unable to replicate any license validation issue at our
end. For your convenience, we have attached the working sample.
Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/license-1845199582.zip
As a result, we suspect that this problem is caused by
the.cache file in your application.If you follow the below steps to install the
packages and try again registering the license key, the issue will be resolved.
1. Delete the @Syncfusion folder from node_modules and the
package-lock.json file from the root folder.
2. Also, clear npm .cache if it is generated at your end.
3. Run the ‘’npm install" command to install the
node_modules.
4. After installing the packages in node_modules run the
license activation command "npx syncfusion-license activate "
Refer to the below documentation for registering the license
key using the npx command:

If the issue persists, please share with us a reproducible
sample.
