Sanic: Error: Overlong 2 byte UTF-8 sequence detected when encoding string

[rainyear]

while return json(doc), doc is fetched from mongodb.

Hmm, it's possible the encoding of the contents of doc are not utf-8. Do you have some example code I could see?

[rainyear]

Finally I found out that this was caused by the problem of json(mongodb.ObjectID), mongodb.ObjectID cannot be serialized by the json method.

@rainyear in pandas the same problem and the same solution. just remove _id and everything fine.
