Issue adding attachments to documents in CouchDB - json

Question

I'm having problems adding attachments in CouchDB. First off, when I ran the test suite in Futon I got two errors - one in attachments, and another in replication. The error specific to attachments isn't particularly helpful -
name
attachments
status
error
duration
6112
details
0
Exception raised: {}
Some internet commentary says that a few errors in the test suite is perfectly normal, so I moved on. However, attachments are definitely not working properly, either via Futon or Curl. In Futon, the file will generally attach, but only after I click cancel on the upload - i.e. it hangs on the upload progress bar indefinitely until I click cancel. I'm accessing futon on a remote machine via ssh -L5984:127.0.0.1:5984 root#myServer and then pointing Firefox at localhost:5984/_utils/. I don't know if that could be making a difference.
When I try to upload via Curl, using the command
curl -vX PUT http://127.0.0.1:5984/albums/6e1295ed6c29495e54cc05947f18c8af/ artwork.jpg?rev=9--43332bfae07884c683b50ffd4b8ee18c --data-binary #artwork.jpg -H "Content-Type: image/jpg"
I get:
Host: 127.0.0.1:5984
Accept: /
Content-Type: image/jpg
Content-Length: 11205
Expect: 100-continue
< HTTP/1.1 100 Continue
< HTTP/1.1 400 Bad Request
* HTTP error before end of send, stop sending
{"error":"bad_request","reason":"invalid UTF-8 JSON"}
The log file shows:
[debug] [<0.103.0>] 'PUT' /albums/6e1295ed6c29495e54cc05947f18c8af/ {1,1}
Headers: [{'Accept',"*/*"},
{'Content-Length',"11205"},
{'Content-Type',"image/jpg"},
{"Expect","100-continue"},
{'Host',"127.0.0.1:5984"},
{'User-Agent',"curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3"}]
[debug] [<0.103.0>] OAuth Params: []
[error] [<0.103.0>] attempted upload of invalid JSON (set log_level to debug to log it)
Followed by a huge block -
[debug] [<0.103.0>] Invalid JSON:
<<255,216,255,224,0,16,74,70,73,70,0,1,1,0,0,1,0,1,0,0,255,219,0,132, ... , etc
The final two lines in the log that are relevant to the attempted upload are
[info] [<0.103.0>] 127.0.0.1 - - 'PUT' /albums/6e1295ed6c29495e54cc05947f18c8af/ 400
[debug] [<0.103.0>] httpd 400 error response: {"error":"bad_request","reason":"invalid UTF-8 JSON"}
Does anyone have any idea what is going on here? I tried wrapping the string in the curl request around ' ' in case bash was eating the quotes, it made no difference.

Answer 1

There is a spurious space in your curl command after the slash between the doc id and the attachement:
...f18c8af/ artwork.jpg?...
^
Does it work when you remove it?

Answer 2

There were two problems. The first was the spurious space that Simon pointed out - tyvm. The other problem was where the rev-x details are placed. I was using the format in the book http://guide.couchdb.org/editions/1/en/api.html.
Original command:
curl -vX PUT http://127.0.0.1:5984/albums/6e1295ed6c29495e54cc05947f18c8af/ artwork.jpg?rev=9--43332bfae07884c683b50ffd4b8ee18c --data-binary #artwork.jpg -H "Content-Type: image/jpg"
Working command (space removed & rev placed in the correct order):
curl -vX PUT http://127.0.0.1:5984/albums/6e1295ed6c29495e54cc05947f18c8af/attachment?rev=9-43332bfae07884c683b50ffd4b8ee18c --data-binary #artwork.jpg -H "Content-Type: image/jpg"
