Suddenly getting "get block hash list failed" errors
I am using goar as well as arsyncer. Arsyncer has always worked just fine both locally and in my hosted environment, and goar has been working fine locally just fine as well.
Starting sometime in the past few days I'm suddenly getting an error:
pNode.GetBlockHashList() module=syncer err="get block hash list failed"
I'm getting this when running Arsyncer, or Goar, and both locally and in cloud. I created fresh new Ubuntu 22.04 instances to test it on also and tried that with versions of go 1.15 through 1.20.
I'm opening this ticket to find out if this is somehow just isolated to my code or if something has changed with the way blocks are pulled from peers.
Support context.Context
I wish I could use this library but because it does not support go's context.Context I can't reliably use it. This library obviously performs operations over a network and it is common practice to use a context so that network operations can be cancelled by the context, either by manual cancellation or deadline. The go http package supports contexts with functions like http.NewRequestWithContext.
Even if I use contexts and goroutines to disregard the response of a *goar.Client when a context times out for example, there is no way to stop the execution of a function. If I were to be downloading content from arweave, it would continue downloading despite the context cancelling, and the program continuing running.
The only workaround I can see is manually setting a timeout on the http client, but this is bad practice and not predictable.
create arweave wallet account using go lang.
Is it possible to create arweave wallet account ?. Below is the scenario.
User can provide seed phrase if exists or create a new seed phrase to create new arweave wallet account.

}What could be wrong here?
Can goar support uploading file with streaming style?
Current API only support uploading bytes([]byte). It is obviously not good for upload big files(e.g., video files) at same time.
Shall we consider arweave API like S3?
PutObject(reader io.Reader, objectSize int64, opt PubObjectOption) (PutObjectResult, err error)
Thanks a lot
send to bundler request failed; http code: 402
Hello, I am trying to use the bundler to upload files but every time I attempt to submit a bundle I receive this error:
send to bundler request failed; http code: 402
this is my flow for finalizing:
_, err := bm.Wallet.Client.BatchSendItemToBundler(bm.BundleItems)
if err != nil {
return err
}
bd, err := utils.NewBundle(bm.BundleItems...)
if err != nil {
return err
}
_, err = bm.Wallet.SendBundleTx(bd.BundleBinary, nil)
if err != nil {
return err
