[open_channel] No error message when funding_amount is less than open_channel_auto_accept_min_ckb_funding_amount #546
Description
Send an open_channel request to node A to establish a channel with node B. However, since the funding_amount parameter in the open_channel request is less than the open_channel_auto_accept_min_ckb_funding_amount configured on node B, the request never succeeds (no new channel appears in list_channels). There is no useful message in the response of open_channel or in node A’s logs (even with the log level set to debug). This significantly increases the time required for users to diagnose the issue. Suggest improving this.
