Store the replacement in rcv.SlackConfigs.
With gopkg.in/yaml.v2, a null element remains a nil *slack.SlackConfig; strict decoding does not reject it, and SlackConfig.UnmarshalYAML is not called. When global Slack defaults allow the entry to pass Config.UnmarshalYAML, the range variable assignment does not update the slice. resolveFilepaths later dereferences the nil element through cfg.HTTPConfig and can panic.
Proposed fix
- for _, sc := range rcv.SlackConfigs {
+ for i, sc := range rcv.SlackConfigs {
if sc == nil {
sc = &slack.SlackConfig{}
+ rcv.SlackConfigs[i] = sc

Validate update_message after credential merging.
SlackConfig.UnmarshalYAML calls Validate before receiver-level credential merging. DefaultSlackConfig leaves APIURL nil, so configurations using app_token, app_token_file, or inherited global app credentials reach this line with a nil APIURL. The String() call then dereferences the nil SecretURL and panics during configuration loading. Receiver normalization sets the bot endpoint only afterward.
Move this check after credential merging, or handle token configurations before calling APIURL.String().
