error reading server preface: http2: frame too large

[ycryptx]

Can you include more information to help me reproduce this error?

[99Kies]

I'm actually testing my own testnet.

grpc: vota-testnet-grpc.dorafactory.org rpc: vota-testnet-rpc.dorafactory.org

chaincannon -chain cosmos -endpoint vota-testnet-grpc.dorafactory.org:443 -duration 60 -tx-file ./example/cosmos/data/run1.json  -tx-file ./example/cosmos/data/run3.json -tx-file ./example/cosmos/data/run4.json

[ycryptx]

@99Kies Could you also include the full error log you get?

[99Kies]

sure

@99Kies What's the Tendermint RPC endpoint (including port #) for your node?

[99Kies]

@ycryptx rpc: https://vota-testnet-rpc.dorafactory.org:443

[ycryptx]

@99Kies I just merged a potential fix, please pull the latest master and run make install

Then call:

chaincannon -chain cosmos -endpoint vota-testnet-grpc.dorafactory.org:443 -tendermintEndpoint vota-testnet-rpc.dorafactory.org:443 -duration 60 -tx-file ./example/cosmos/data/run1.json  -tx-file ./example/cosmos/data/run3.json -tx-file ./example/cosmos/data/run4.json

I added a flag that should have been there before (tendermintEndpoint)

[99Kies]

Bro, Can you run it successfully?

I have same error.

@99Kies Does your chain implement the bank module?

[99Kies]

yes, we have. @ycryptx

[ycryptx]

@99Kies Are you able to run the example using the Docker-Compose example test chain? i.e.

make setup-example

In another terminal window:

make run-example

[99Kies]

@ycryptx I'm getting the same error.

[99Kies]

Is it somewhere in the code that limits the size of the http packet?

[ycryptx]

@99Kies Awesome, thanks for running that. I identified the issue: it has something to do with the OS HTTP_PROXY settings. Please pull master and run the example again and let's see if it solved things.

[99Kies]

It doesn't solve the problem.

[ycryptx]

@99Kies Is your Cosmos node deployed on the cloud behind a network interface / proxy? What's likely happening is that Chaincannon expects a grpc response but your node is responding with an HTTP packet.

[99Kies]

It doesn't solve the problem.

I have this problem in my local test as well.
