[Star wars] I am a mid ranking imperial officer on board the Executor who has made a mistake on a command decision. When confronted by Lord Vader I told the unaltered truth and made no attempts to hide my mistake. Prior to this I had a flawless record. Will I survive the encounter?

It has been two years since the empire lost the death star and a general broadcast order said to conserve replacement parts due to a supply shortage. 

I was in command of a weapon's battery, one of the power conduits showed slight signs of damage but remained serviceable for standard use. I made the command decision not to replace it.

In our last encounter with a rebel ship, lord Vader attempted to engage the cannons at a higher power level than standard. Doing so overloaded the conduit and caused my canon to misfire. My team was able to replace the conduit within half the average repair time however the rebel ship escaped. Its shields had failed right before it entered hyperspace and it is likely even one more shot would have crippled it.

I have taken full responsibility for the failure of my canon and attempted no subterfuge. What will lord Vader do with me?

Edit: Bonus question, how would it differ from Grand Admiral Thrawn?

Most likely, yes.  Vader is actually pretty chill as long as you follow basic workplace etiquette.  Don't make fun of the guy's disability or his religion, and you will most likely survive any encounter with him.  Even gross negligence would really only get you a brief choking as a warning.
