Bug: Panic in croc during runpodctl Transfer Operations

[enriquebarco]

Description:

I'm encountering a panic error when using runpodctl for file transfers. The error occurs during the sendData function in the croc package. Below is the stack trace:​

goroutine 122 [running]:
github.com/runpod/runpodctl/cmd/croc.(*Client).sendData(0x140000ee248, 0x8)
    /home/runner/work/runpodctl/runpodctl/cmd/croc/croc.go:1806 +0x744
created by github.com.runpod.runpodctl/cmd/croc.(*Client).updateState in goroutine 10
    /home/runner/work/runpodctl/runpodctl/cmd/croc/croc.go:1634 +0x500

Steps to Reproduce:
Initiate a file transfer using runpodctl send .​ (my file is around 430 GB)
Observe the panic during the transfer process.​

Expected Behavior:
The file transfer should complete without triggering a panic.​

Environment:
OS: Mac M2
runpodctl Version: v1.14.4

Additional Information:
This issue is causing significant disruptions and financial implications due to failed transfers. I've attempted the following troubleshooting steps without success:​

Ensured that each transfer is run sequentially to avoid concurrency issues.​
Updated runpodctl to the latest version.​
Verified network stability during transfers.​
Any guidance or fixes to resolve this issue would be greatly appreciated.
