Hi Kichoul,
 
Greetings from Syncfusion.
 
We have created a sample as per your provided code snippet with SfTabView and we are not able to reproduce the log you have mentioned in the output window. The error seems to be related to Resource files used in the Application.

Can you please whether it appears only when the TabView is used and if possible share us the sample which will be helpful for us to validate the issue.
 
We have attached the sample we have created which is available in the below link.
 
sample:

Please let us know if you have any concern.

Regards,

Ruba Shanmugam.
