Invalid licence key

[Nemanja Pavlovic]

At the moment I am getting the error for my project
' This application was built using a trial version of Syncfusion Essential Studio. To remove the license validation message permanently, a valid license key must be included. Claim your free account'

But I added community license in my Angular application and only once. But I am still getting the same error as I try to use it. Can you help me somehow?

Hi Nemanja Pavlovic,

Greetings from Syncfusion.

We have evaluated the issue you reported and understand that you are facing difficulties while registering the license in your application. Regarding this issue, please ensure that you are using the same major version for all Syncfusion components. Our Syncfusion licenses are version-specific, and if multiple major versions of our components are used in the same application, it can create version conflicts. Therefore, please make sure that you use the same version for all Syncfusion components.

 

We would like to inform you that, if we generate a key for the major version (i.e., v27.X.XX), any key generated under the major version (v27.X.XX) can be utilized for all the minor versions in (v27.X.XX). But if you want to utilize our next major version (i.e., v28.X.XX), it is necessary to generate a new license key for the latest major version.

 

And also use the ~ sign instead of ^, since it is best practice to avoid any major version upgrade conflict, and it will bring the latest patch of the current version.

However, kindly ensure that the license key registered as mentioned in the documentation using register method. we would like to convey that the "register license" method should be called from the root folder of the application. This step registers the license globally for our components.

You can register the license through the npx command as an alternative approach. Please find below the documentation link for registering the license through the npx command:
Register Syncfusion License key using the npx command

 

Additionally, this issue may occur due to duplicate packages installed in your application. Follow the below steps to resolve the issue.

• Delete the @Syncfusion folder from node_modules and the package-lock.json file from the root folder.
• Clear the npm cache file at your end: npm cache clean --force. 
• Update our packages to the same major version. For example, if you are using a version like (i.e., v27.1.XX), use the same version for all the Syncfusion components in the package.json file. 
• Run the ‘’npm install” command to install the Syncfusion packages again.
