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.
**added entire template
