Failed to get block template: Server returned rpc error Server error: RPCModuleIsDisabled

[pranavt61]

Environment

• CKB version: docker image nervos/ckb:v0.38.0
• Chain: mainnet
• Operating system: Linux
• Arch: x64
• Installation: Docker-compose

Describe the bug

After getting the docker container running, I tried the RPC command 'get_block_template' and received an error

{
"jsonrpc":"2.0",
"error":{
"code":-4,
"message":"RPCModuleIsDisabled: This RPC method is in the module Miner. Please modify rpc.modules and
block_assembler in ckb.toml and restart the ckb node to enable it."
},
"id":2
}

This is what my ckb.toml looks like:

Is there anything I am missing in the config?
Any help would be appreciated, thank you!

Can't reproduce, please confirm that the configuration file has been modified, and the modified configuration file is used when ckb restart

What's your compose file? How do you modify ckb.toml and restart the node?

It seems that your config file is not effective, maybe:

• You have not restarted the ckb run process
• Your ckb.toml is not persisted when the process restarts.
• You have edited the wrong ckb.toml.

Here is my ckb container in the docker compose file

The ckb.toml file is in the "./ckb/" directory which is transferred into a volume. I am pretty sure the node is loading the cbk.toml because when I change a field to intentionally crash the node, it crashes:

Just found this in the logs:
ckb-node_1 | 2020-12-01 01:21:43.303 +00:00 main INFO main Miner is disabled because block assmebler is not a recommended lock format. Edit ckb.toml or use ckb run --ba-advanced to use other lock scripts

Am I missing something in the block_assember part of the toml? Screenshot of the block_assember section in the original post

the standard format of the args in block_assembler section should be 20 length of hex string, for example, '0x8d627decece439977a3a0a97815b63debaff2874'

Works fine now, thanks for the help!
