I have fixed both problems. Closing.

In fact even with nextword install but with no NEXTWORD_DATA_PATH setup. I still got errors.

So from my point of view, there are two issues:

1. I did not enable nextword as a source. But nextword crash the ddc.vim
2. Would be better that the plugin does not crash even if some sources enabled by failed to work. Instead, showing warning messages would be helpful.
