saving of converted adapter

[rankofootball]

When I save base and adapter in LoRA-format

model.save_pretrained(new_model, convert_pissa_to_lora="pissa_init")

I get the error

HFValidationError: Repo id must use alphanumeric chars or '-', '_', '.', '--' and '..' are forbidden, '-' and '.' cannot start or end the name, max length is 96: ''.

Without the "pissa_init" it saves normal.

Any idea?
