Sharing another stumbling block that took forever to figure out…
I kept getting “Access to the path ‘CustomerSolution.zip’ is denied.” when trying to build out the solution in Solution Workbench. Nothing on this anywhere.
Turns out I had a bad QueryID on a BAQ that had spaces in it… no idea how that got there. Solution built fine when I removed it from the list.
Another cause of this error was having too many BAQs in the list. Probably hitting some timeout or file size limit.
