New-AzureRmResourceGroupDeployment : A parameter cannot be found that matches parameter name '_artifactsLocationSasToken'

Question

I was changing an ARM template (including linked templates) that was working for months. After building successfully, when deploying I got the error

New-AzureRmResourceGroupDeployment : A parameter cannot be found that matches parameter name '_artifactsLocationSasToken'

Answer 1

I knew that uploading artifacts sometimes is a somewhat sensitive business, so I checked out corresponding posts to get hints - among them this one that seemed helpful. But nothing had an effect, so I took a break.

After coming back I thoroughly checked my template and

1. found one right parenthesis too much in a medium complex concat/parameter/variable expression (highlighted with a 1 character wide squiggly line)
2. found that I missed closing curly braces and square brackets at another place (after applying a "Format Document" on the template)

Hence my take on that: do not rely on the Build process; don't get misled by the error message; when having this kind of error re-check the template, even shrink it down to isolate invalid areas
