Hi,
I am facing some below strange error while importing a solution (for the first time) in Dynamics 365 online environment. Error message is not clear and not getting download log file option to identify the problem. But there is a 'Help me resolve this issue' link which takes to a support page: "Error code 80040203" (Invalid Argument) error occurs when attempting to import a solution into Dynamics 365 (microsoft.com), but still the error persists even after following the solution provided.
Any help to resolve this error is appreciated. Thanks
