Hello Ibraima,
it's not the broblem, if you don't have the snaprestore you can not do the snaprestore functionality, but you can continue to use the plugin.
what is your ONTAP version and storage mode (7mode or storage virtual machine)?
In 8.2.1, licence query api is deprecated and the new API is introduced. if you are using 8.2.1 - 7mode, Please wait for a 1-2 weeks, the new patch version will be uploaded. if you are not using 8.2.1 - 7mode, you don't have any issue to deploy the plugin.
Please let me know if you need any more help
regards,
Karthikeyan.N
