overlay render not working in devdocs buffers

[seagle0128]

I got this error while translating in a devdoc buffer, generated by devdoc.el.

[output error] Error in translation, error 
{"statusCode":400,"errorMessage":""}

My config is:

(setq gt-default-translator (gt-translator

(gt-taker :text 'buffer :pick 'fresh-word :if 'read-only)

I guess: all words in the buffer are joined and sent to the server, it's too long and be denied by the server.

You can change to (gt-taker :text 'paragraph :pick 'fresh-word :if 'read-only) to check if the error still exists.

Correct! I changed my configuration and close it.
