slice bounds out of range Error When Downloading File from RPC Endpoint

[Josephtran102]

Description:

When attempting to download a file from certain RPC endpoints using the 0g-storage-client, I encounter a runtime error: slice bounds out of range. This error occurs consistently when using specific endpoints but not others.

1. Steps to Reproduce:

Upload a file to a storage node using the following command:

./0g-storage-client upload \
--url https://evm.rpc2.0gchain.josephtran.xyz \
--contract "0x8873cc79c5b3b5666535C825205C9a128B1D75F1" \
--key $PRIVATE_KEY \
--node "https://storage-node3.0gchain.josephtran.xyz/" \
--file $HOME/0g-storage-client/test.txt

2. Attempt to download the file from the same node using:

./0g-storage-client download \
--node "https://storage-node3.0gchain.josephtran.xyz/" \
--root 0xf6cec803a2c135fd75e0e6bcbcb5ff48e4774b62e762cf5e475d3a8247601d6b \
--file /root/0g-storage-client/outtt.test100.txt

The download succeeds without errors.

3. Attempt to download the same file from different RPC endpoints using:

./0g-storage-client download \
--node "https://storage-node1.0gchain.josephtran.xyz/" \
--root 0xf6cec803a2c135fd75e0e6bcbcb5ff48e4774b62e762cf5e475d3a8247601d6b \
--file /root/0g-storage-client/outtttt.test100.txt

or

./0g-storage-client download \
--node "https://rpc-storage-testnet.0g.ai" \
--root 0xf6cec803a2c135fd75e0e6bcbcb5ff48e4774b62e762cf5e475d3a8247601d6b \
--file /root/0g-storage-client/outttttt.test100.txt

Observed Results:

The command fails with the following error:

panic: runtime error: slice bounds out of range [:-83]

        /root/0g-storage-client/common/parallel/serial.go:37 +0x1bf

Expected Results:
The file should download successfully from any RPC endpoint.

Environment:

0g-storage-client 
0g-storage-node: v.0.3.4
Operating System: Ubuntu 22.04.4 LTS
Node URLs:
Working: https://storage-node3.0gchain.josephtran.xyz/
Failing: https://storage-node1.0gchain.josephtran.xyz/, https://rpc-storage-testnet.0g.ai

Additional Information:

I have verified that the file uploads and downloads successfully from the working endpoint, and the issue consistently occurs with other endpoints.
I have also checked that all endpoints are reachable and the network connection is stable.
Logs:

Include any relevant logs if necessary (e.g., from 0g-storage-client or the node).
Suggested Fix:

Investigate the ParallelDo method in download_parallel.go for possible issues with handling slice bounds or RPC responses.
