2017 Sprinter slide issues

Went on a trip with our camper, went to put the large slide in and the L bracket holding the cable to the slide ripped right off. What do i do next. I do have a warranty but I don’t think this is repairable based on how the slides are constructed. Looks like aluminum stock behind the bracket. I was able to get the slide in 3/4 of the way. Worth an insurance claim?
