I run MC v2.2 and when I try to add a product I get the spinning wheel & I have this error 404:
Any ideas? This file should be generated...
If you have multiple language installed in your system,
run deployment command with multiple languages as spaces,
php bin/magento setup:static-content:deploy [lang_code] [lang_code]
Ex. you have english and french store run below command,
php bin/magento setup:static-content:deploy en_US fr_FR
