Data collator issue: ValueError: You should supply an encoding or a list of encodings to this method that includes input_ids, but you provided []

Hello all,

While attempting to train a PeftModel using Trainer and DataCollatorForSeq2Seq, I get the following error:
ValueError: You should supply an encoding or a list of encodings to this method that includes input_ids, but you provided [].

I would greatly appreciate any tips!
