```
def create
@work = current_user.works.build(permitted_params.work)
if @work.save
render json: @work, status: :created
else
render json: { status: 'error', message: @work.errors.full_messages }, status: :bad_request
end
end
```

删除了对用于将自定义对象编码为JSON的encode_json挂钩的支持。此功能已提取到activesupport-json_encoder gem中。 (相关拉动请求/更多详情)
Because activesupport doesn't encoding invalid code anymore. Add activesupport-json_encoder gem to Gemfile fix this issue.

Just adding if it can be of help to someone who is trying to find the solution to the error , while trying to write .jpg or any image files.
在尝试编写.jpg或任何图像文件时,只需添加它是否可以帮助那些试图找到错误解决方案的人。
"wb" instead of "w" in File.open(filename,'wb') has solved this issue for me.
File.open中的“wb”而不是“w”(filename,'wb')已经为我解决了这个问题。
