How can I use forge with a local geth light node?

[CaledoniaProject]

I'm trying to use forge with a local geth node:

geth --syncmode light --datadir geth-light --mainnet --http

Then I created an empty project

forge init

And run it against the local geth RPC:

forge test -vvv --fork-url http://127.0.0.1:8551

But it doesn't work:

# RUST_BACKTRACE=full forge test -vvv --fork-url http://127.0.0.1:8551
[⠔] Compiling...
No files changed, compilation skipped
The application panicked (crashed).
Message:  could not instantiate forked environment:
Failed to get latest block number

Context:
- Deserialization Error: expected value at line 1 column 1. Response: missing token

What's wrong?

The default port is 8545, you are specifying 8551 in Forge without setting it to 8551 in geth.

@onbjerg Thanks, now I got:

Is there anything else I should do?

Seems like your light node is not connected to any nodes that can provide the data Forge is asking for. It is likely that you are firewalled and not getting any good peers.
