Unexpected end of input

[babolivier]

When trying to create an object in the DataSystem with cozydb@0.0.19 for a side project, I get this error in the DataSystem logs:

SyntaxError: Unexpected end of input
    at Object.parse (native)
    at parse (/usr/local/cozy/apps/data-system/node_modules/americano/node_modules/body-parser/index.js:65:17)

I just switched to version 0.0.16 for now and it's working fine so far.

Sad. Thank you for reporting.

@babolivier, could you show the code which product this output ?

[babolivier]

Here it is: https://github.com/babolivier/cozy-library/blob/development/server/models/book.coffee#L45
I think it changed a bit since this error, but the way the create method is called is the same (I'll have to make a few tests later today).

[aenario]

I made a few test and am totally unable to reproduce this bug.

Could you please :
1 - give me sample of what the book object is like
2 - add a console.log(opts); at yourproject/node_modules/cozydb/node_modules/request-json-light/main.js#100

Thanks !

Hi @aenario,

Sorry for the delay in my reply.

The book object is defined just above the line I sent you, so I believe you're asking be for an example of the item object, here is one:

{ Author: [ 'Carroll Quigley', 'Pierre Hillard' ],
  Binding: [ 'Broché' ],
  EAN: [ '9782355120626' ],
  EANList: [ { EANListElement: [Object] } ],
  ISBN: [ '2355120625' ],
  ItemDimensions: [ { Height: [Object], Length: [Object], Width: [Object] } ],
  Label: [ 'Le retour aux sources' ],
  Languages: [ { Language: [Object] } ],
  ListPrice: 
   [ { Amount: [Object],
       CurrencyCode: [Object],
       FormattedPrice: [Object] } ],
  Manufacturer: [ 'Le retour aux sources' ],
  NumberOfPages: [ '454' ],
  PackageDimensions: 
   [ { Height: [Object],
       Length: [Object],
       Weight: [Object],
       Width: [Object] } ],
  ProductGroup: [ 'Book' ],
  ProductTypeName: [ 'ABIS_BOOK' ],
  PublicationDate: [ '2015-05-30' ],
  Publisher: [ 'Le retour aux sources' ],
  Studio: [ 'Le retour aux sources' ],
  Title: [ 'Histoire secrète de l\'oligarchie anglo-américaine' ] }

Then I added the console.log(opts); in the file you mentionned, here's the output:

   { accept: 'application/json',
     'user-agent': 'request-json/1.0',

     createServer: [Function],
     _connectionListener: [Function: connectionListener],
     Client: [Function: deprecated],
     createClient: [Function: deprecated] },
  method: 'POST' }

By the way, I obviously checked, and I get the same bug with the current version of the file: https://github.com/babolivier/cozy-library/blob/development/server/models/book.coffee

Hope this'll help.

Ok, Got it !

It is caused by the accents :

> JSON.stringify(a)
'{"test":"accent éguè"}'
> JSON.stringify(a).length
22
> new Buffer(JSON.stringify(a)).length
24

So, we set the Content-Length at 22 but, the byte length is 24, so the DS missed the last two char and bug ensues. I couldn't reproduce because I was testing with ASCII characters only !

Hi @babolivier,
The fix should be available in latest version of CozyDB. could you give it a try please ? Thanks !
