Do you know why when I call the DEX's swap_tokens_fixed_input() through a Pair Contract Proxy in the same shard, why it returns the error "argument decode error (sync result): input too short"? I use the code: let esdt = self.maiar_exchange_pair(pair_address).swap_tokens_fixed_input(swap_token_id, swap_token_amount) .add_esdt_token_transfer(token_id, nonce, amount) .execute_on_dest_context(); You know what could be wrong?
