Add another case "". That way the dynamically generated error below doesn't just show "unknown 'source' field value: " if the source field is empty.

Another solution would be to use the %q format specifier in the below-suggested call to fmt.Errorf(), but that would always put quotes around the value. If that error is then subsequently logged with something like log.Error().Err(err).Msg("whatever"), those quotes will get escaped and things will be uglier than necessary. So that's why I think it's nicer to handle the empty string as a special case, and keep the non-empty-string case without quotes.

Add another `case ""`. That way the dynamically generated error below doesn't just show `"unknown 'source' field value: "` if the `source` field is empty. Another solution would be to use the `%q` format specifier in the below-suggested call to `fmt.Errorf()`, but that would _always_ put quotes around the value. If that error is then subsequently logged with something like `log.Error().Err(err).Msg("whatever")`, those quotes will get escaped and things will be uglier than necessary.

This function could return an error instead of a boolean. That error can then not only be used to communicate what is still missing, but also cover this case. That'll avoid the need to pass a logger to the function.

Unfortunately Gitea does not support multiple comments for the same source line. So I'll reply to the previous one, even though at this line number there is now different code.

		return errors.New("unknown 'source' field value: " + string(config.BlenderExecutable.Source))

This should use fmt.Errorf() instead.
