Magento – how to fix error after deploy:mode: developer

In Magento2, after I created custom.less in myTheme, it does not render file less. so I tried run cli php bin/magento deploy:mode:set developer

then in the admin panel, I get the error:

SyntaxError: missing } after property list


};

I tried removing everything in pub/static except .htaccess and run cli /bin/magento setup:static-content:deploy. but there is no change. Any suggestion? Please help me?

thanks
