azure SQL DB import with copy - azure

Question

I am working on an ARM template that will ask for a comma separated list of db names and then create them using the copyIndex function. This aspect is working great but the next step of my solution is not. What I would like to do next is Import a .bacpac file for each database so that it is ready for use upon completion.
The validation error indicates the issue is with the concat function in the Import resource dependsOn. I have tested it a handful of different ways and can not see where it is wrong.
The exact error message I am seeing is....
Unable to process template language expressions for resource '/subscriptions/xxxxxx-xxxxx-xxxxxx-xxxxx/resourceGroups/testGroup/providers/Microsoft.Sql/servers/testsql/databases/CustomersDB/extensions/import' at line '858' and column '10'. 'The provided parameters for language function 'concat' are invalid. Either all or none of the parameters must be an array.

As far as I know, we couldn't use the copyindex function in the nested resources.
If you run your arm template, you will face this error:
Copying nested resources is not supported. Please see https://aka.ms/arm-copy/#looping-on-a-nested-resource for usage details.'.
So I suggest you move the nested resources as root resources in arm template. Then you could use the copyindex.
More details, you could refer to below arm template:
Notice: Replace the parameter orb with your database name.

I have also test your template, I found there are something wrong with your storage url in import extension. I changed it with primary storage key and url. It works well.
