Can't Retrieve data from archiver. Error: 'NoneType' object has no attribute 'lower', returned

[jeovanevs]

On Ubuntu 14.04.1 with python 2.7.6 After a clean install by:

$ sudo add-apt-repository ppa:cal-sdb/smap
$ sudo apt-get update
$ sudo apt-get install -y python-smap readingdb powerdb2

The folder /var/run/smap was not created, so the archiver process could not start. I' ve created it this way:

$ sudo mkdir /var/run/smap
$ sudo chown -R smap /var/run/smap

And restart the archiver process in supervisorctl.

After that I tried to send the file data.json like the example here and when I tried to retrieve this data in smpa-query using this command select data in ("01/01/2010" , now) where uuid = "d24325e6-1d7d-11e2-ad69-a7c2fa8dba61" or even in the browser at http://localhost:8079/api/data

it returned this error

Error: 'NoneType' object has no attribute 'lower'

Any idea how can I solve this on unitoftime branch.

Thanks a lot. Jeovane @jeovanevs

Hi there,

Can you provide a log of what's happening on the server-side? You may also need to generate an API key using powerdb2 and append that to the end of the add url, e.g. http://localhost:8079/add/<apikey here>

Hi @gtfierro I have created a subscription in* localhost/admim* with an apikey 12345. I have cleaned the log file in* /var/log/archiver.stdout.log* and restarted the archiver. After I send the file data.json as previously mentioned; And tried to see the data in http://localhost:8079/api/data and received that error. Following the log content:

One more thing: how can I see the data directly on Postgre, or on readingdb. Is there a specific table or sequence where this data are saved? Do you have the commands to do this. Thanks.

[gtfierro]

Try adding UnitofTime = "ms" under the Properties tag; I believe this is the issue. The documentation on the wiki was copied directly from another version of sMAP which does not require this field.

Metadata (kv pairs) is stored in Postgres and the timeseries data is stored in readingdb, which you can read about how to use here

It worked like a charm. Thank you!
