Hi Marek,
Greetings from Syncfusion support
We suspect that the issue may occur due to the
following reasons.
Reason 1: 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
npm .cache file at your end.
- Update our
packages to the same major version. For example, if your utilizing version
like (i.e. v20.4.XX) use the same version for all the Syncfusion
components in the package.json file.
- Run
the ‘’npm install” command to install the node_modules.
Reason 2: If Syncfusion components are used with
Cap Symbol (^) in the package.json file there is a possibility of license
banner appearing ever after registering the license and this is one of the
cases of license validation. So, we are suggesting you to use the Tilde (~)
symbol instead of Cap (^) symbol to resolve this issue.
Kindly follow the below steps to resolve this issue
- Delete
the @Syncfusion folder from node_modules and the package-lock.json file
from the root folder.
- Clear npm
cache at your end.
- Remove the
cap (^) symbol before the version number and use the mentioned symbol
Tilde (~) before the version number like
("@syncfusion/ej2-react-buttons": "~20.4.38").
- Run
the "npm install” command to install the packages.
Please
get back to us if you need any further assistance
