I have implemented discovery, getFileInfo, getFile and putFile in my own WOPI host. All are working fine except putFile.  
When I change my document it is routed to my putFile function, but the body which is expected to have the file content, is empty!

Can anybody help why that happened?

```
 route('POST', '/wopi/files/:fileId/contents', (req, res) => {
    console.log(' *********putFile routed*********')
    if (req.body) {
      console.dir( req.body)
      res.sendStatus(200);
    } else {
      console.log('Not possible to get the file content.');
      res.sendStatus(404);
    }
  });
```

If you turn debugging up to ‘trace’ - what do the logs say about posting the file on save ? =) there is very verbose loolwsd.log logging indeed if you turn it to maximum.

Thank you for your reply.

I checked the loggs, It says that it successfully upload the file contents. the logs are exactly the same as logs produced via [example project](https://github.com/CollaboraOnline/collabora-online-sdk-examples//tree/master/webapp/reactjs) which its putFile has content in its body.

So should I do something in my project to make it work?

Actually the problem solved, it was about using [body-parser](https://www.npmjs.com/package/body-parser) in my wopi host code.

Thanks.
