Purge parachain issue

I want to purge my parachain collator node, but I got this error

Input("Error parsing spec file: missing field `relay_chain` at line 143 column 1")（cannot purge parachain）

This is the command I used to purge my parachain

./target/release/parachain-collator  purge-chain --base-path /tmp/parachain/alice --chain rococo-custom.json

This is the command I used to run this parachain-collator

./target/release/parachain-collator \
--alice \
--collator \
--force-authoring \
--parachain-id 2000 \
--base-path /tmp/parachain/alice \
--port 40333 \
--ws-port 8844 \
-- \
--execution wasm \
--chain rococo-custom.json \
--port 30343 \
--ws-port 9977

Thank you so much for your help!

Solution 
  • ./XXX/parachain-collator purge-chain --base-path <your collator DB path set above>

    no need args for chainspec.
