non-recognition of the size of the sampling vial IN HEAD SPACE 7697A

Hello everyone. I need help

I have a GC7820 connected to a HS7697A.
when I launch a sequence, at the time of pressurization and extraction for injection into the GC, the sequence is interrupted and the screen displays "incorrect vial size found on vial 4''. and I notice that when the vial is removed that the latter was not pierced by the needle. is there an explanation for this? 

who can help me please?
