mendeley.exception.MendeleyException: Catalog document not found following example

[silpol]

I have fetched git repo and made "pip install -r requirements.txt" and checked that everything has installed.

silpol@hostname:/tmp/mendeley-api-python-catalog-example$ pip install -r requirements.txt -U
Requirement already up-to-date: PyYAML==3.11 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 1))
Requirement already up-to-date: argparse==1.2.1 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 2))
Requirement already up-to-date: arrow==0.5.0 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 3))
Requirement already up-to-date: certifi==14.05.14 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 4))
Requirement already up-to-date: future==0.14.3 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 5))
Requirement already up-to-date: memoized-property==1.0.2 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 6))
Requirement already up-to-date: mendeley==0.3.0 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 7))
Requirement already up-to-date: oauthlib==0.7.2 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 8))
Requirement already up-to-date: python-dateutil==2.4.0 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 9))
Requirement already up-to-date: requests==2.5.1 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 10))
Requirement already up-to-date: requests-oauthlib==0.4.2 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 11))
Requirement already up-to-date: six==1.9.0 in /usr/local/lib/python2.7/dist-packages (from -r requirements.txt (line 12))
Requirement already up-to-date: wsgiref==0.1.2 in /usr/lib/python2.7 (from -r requirements.txt (line 13))

Then I re-used OAuth credentials from previous test. Then launched script as described in readme. It looks like OAuth passed just fine. Then I get prompt

Enter a DOI:

for which I provide DOI for existing document 10.1145/1815961.1816021

and then I get exception

silpol@hostname:/tmp/mendeley-api-python-catalog-example$ python mendeley-catalog.py 
Enter a DOI: 10.1145/1815961.1816021
Traceback (most recent call last):
  File "mendeley-catalog.py", line 12, in <module>
    doc = session.catalog.by_identifier(doi=doi, view='stats')
  File "/usr/local/lib/python2.7/dist-packages/mendeley/resources/catalog.py", line 47, in by_identifier
    raise MendeleyException('Catalog document not found')
mendeley.exception.MendeleyException: Catalog document not found

Is this expected behaviour or malfunction?

[silpol]

what is even more interesting - if I do not change anything and just type in different DOI, literally 10.1016/j.rser.2015.02.031 for another existing article - it goes just fine

silpol@hostname:/tmp/mendeley-api-python-catalog-example$ python mendeley-catalog.py 
Enter a DOI: 10.1016/j.rser.2015.02.031
"Early adopters boosting the diffusion of sustainable small-scale energy solutions" has 0 readers.
silpol@hostname:/tmp/mendeley-api-python-catalog-example$

and just as matter of a fact. both DOI - 10.1145/1815961.1816021 and 10.1016/j.rser.2015.02.031 make perfectly resolved to original pages by simple DOI verification tool, so now it looks more like bug to me.

Hello silpol,

Receiving a 'Catalog document not found' error is a valid response as our catalog may not have that particular DOI.

Using CrossRef to check if it's a valid paper is OK but it does not mean it will be in our catalog as we don't have all CrossRef papers.

I have now made your paper "Debunking the 100X GPU vs. CPU myth: ..." available in our catalog.

We are trying to plan some catalog improvements so stay tuned.

ah, ok, so it is exception on lack of record in your DB. ok, case closed.
