missing value for --method

Error message

missing value for --method

What it means

`openhuman call --method` requires the RPC method name as the next token; the flag was the last argument. The value is consumed unconditionally, so only end-of-args triggers this — a following flag would be taken as the method name and fail later at registry lookup.

Solutions

1. Pass the method: `openhuman call --method openhuman.config_get`
2. Check usage with `openhuman call --help`
3. If you typed only `--params`, remember `--method` is required (it has no default)

Example fix

# before
openhuman call --method
# after
openhuman call --method openhuman.config_get --params '{}'

# bash: refuse to invoke call without a method
METHOD="${METHOD:?openhuman call requires --method <rpc-method>}"
openhuman call --method "$METHOD"

When it happens

Trigger: `openhuman call --method` as the final token; a script dropping the method half of the pair.

Common situations: Building `call` invocations from variables with the method empty/missing; command history editing that deletes the value.
