Wallet can communicate over http to node, but can't get info from server on Docker

[MatthewDarnell]

I'm running 2 Docker containers. One for a node, another for the wallet. The wallet can see the grin node just fine, I can query it over curl. However, the wallet can't seem to get any info from it.

I can hit the grin node container from the wallet container:

root@grinwallet:/wallet# curl -u grin:password http://grin:3000/v1/status
{
  "protocol_version": 1,
  "user_agent": "MW/Grin 1.0.0",
  "connections": 13,
  "tip": {
    "height": 10282,
    "last_block_pushed": "000001458659734b99e754c76954d60cedba95a20ef4d86a3c52436927733d45",
    "prev_block_to_last": "000005d24cce12a0e48330782181eceea5d38a506e970f0ca376caa1cb43eef4",
    "total_difficulty": 4794038959825
  }
}

I can get its api commands:

root@grinwallet:/wallet# curl -u grin:password -D -- "http://grin:3000"
[
  "get blocks",
  "get chain",
  "post chain/compact",
  "post chain/validate",
  "get chain/outputs",
  "get status",
  "get txhashset/roots",
  "get txhashset/lastoutputs?n=10",
  "get txhashset/lastrangeproofs",
  "get txhashset/lastkernels",
  "get txhashset/outputs?start_index=1&max=100",
  "get pool",
  "post pool/push",
  "post peers/a.b.c.d:p/ban",
  "post peers/a.b.c.d:p/unban",
  "get peers/all",
  "get peers/connected",
  "get peers/a.b.c.d"
]

However, I cannot get the wallet to get info from the node:

root@grinwallet:/wallet# grin wallet -p 'password' -r "http://grin:3000"  info

Looks like I had a simple config option in my grin-wallet.toml set to the wrong path after all! Anyway, it would be really nice to have failed wallet commands return the error code. In this case, grin was returning 401 Unauthorized, which would have really helped me track it down quicker.

Had the same problem, just to clarify, in my case solution was to set

node_api_secret_path = "/path/to/a/file/containing/the/secret"

In grin-wallet.toml to lead to file which contains .api_secret same as one on the Grin node.
