Source and Destination Chain ID

[moesaleh]

Hello,
What's the recommended source and destination id?
I used this:
"cross_chain_config": {
"source_chain_id": 1,
"dest_chain_id": 56,
"monitor_channel_list": [1, 2, 3, 8, 9],
"competition_mode": true

but it generates a lot of transaction errors, I appreciate your response

it's right

It generated a lot of transactions with errors when I used this configuration, I just need to understand what's the cause of the transactions errors?
