Can't create an application with binary paramters

[keyulong]

I'm trying to create an application in our workspace.

But the datasource I'm currently using contains multiple combined excel files, where a few binary paramters are included. Therefore, after I published the dashboards and datasources in our workspace, I was not able to create an application becasue binary paramters are not supported in application.

Could anyone please help me with this issue? How am I supposed to keep the datasource unchanged but still able to create an application? 

Thanks!
