TR069 - .alter script and /tool fetch

I’m having problems with TR069 and “3 Vendor Configuration File” script (.alter)… All OK but when I do a /tool fetch url=“…” dst-path=… script stops and genieacs informs me about a “Script execution error”.
Can an .alter script perform a /tool fetch?

Thanks, we fixed this issue in the next RC version that will come out this week. Please see if it works after you upgrade (when it comes out)

It works perfectly, thank you!
(tested on RB2011 with 6.42.rc37)
