Problem with Iapp f5.vmware_view_1.2.0

Hello,

When I trying to create a Iapp by using the template, I've got the bellow, any idea why ?

script did not successfully complete: (can't read "::client__http_compression": no such variable while executing "subst $substa_out" invoked from within "if { [info exists [set substa_in]] } { set substa_out [subst $$substa_in] set substa_out [subst $substa_out] } else { ..."
