Getting 9001 - Unexpected Server Error

[Aaron Somal]

Hi,

We're getting the 9001 error code randomly on this request:

http://api.7digital.com/1.2/artist/details?artistId=473615&oauth_consumer_key=OUR_CONS_KEY&country=uk

This happens despite the previous three requests (which happen
directly before, with identical URLs but different artistId's), which
work fine. The request works fine on our local dev versions, but
errors on our live server.

Your API Docs mention that we should contact you when we get an error
code above 7000.

Any ideas on what might be causing this?

Aaron,

We just experienced a very brief outage with our loadbalancer setup, but this has been fixed.

Please could you try again and let us know if you are still experiencing problems.

Thanks,
Chris

Hi Chris,

Unfortunately we're still experiencing this issue.

Hello Aaron,

we're not able to replicate the bug, can you tell us if your dev has any differences from live? Different keys, parameters, anything else?

Would be good to get some copies of the responses if possible, including headers.

Thanks

Hi Goncalo,

The only difference is that our dev version runs locally, while the
live server runs from a remote server. The request is sent in exactly
the same way with the same key and parameters.

The response code is:
<?xml version="1.0" encoding="utf-8" ?><response status="ok"
version="1.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://api.7digital.com/1.2/static/
7digitalAPI.xsd" ><artist id="473615"><name>Veronica Falls</
name><sortName>Veronica Falls</sortName><url>http://www.7digital.com/
artists/veronica-falls/?partner=1375</url><image>http://cdn.
7static.com/static/img/artistimages/00/004/736/0000473615_150.jpg</
image><bio><text></text></bio></artist></response>?<?xml version="1.0"
encoding="utf-8" ?>
<response status="error" version="1.2">
<error code="9001">
<errorMessage>Unhandled 7digital API server error.</errorMessage>
</error>
</response>

It seems that we get a legitimate response, but an error code is also
attached to it.

Hey,

I haven't seen this behaviour before, can you curl the request? please send us a manual request including headers.

We don't have more than one status code per response, are you merging or threading requests in any way? 

Thanks

Hi,

We've tried with a CURL request and this responds fine.

We've also noticed the earlier response contains 2 different XML
declarations:

Part 1 (correct response) -

<?xml version="1.0" encoding="utf-8" ?><response status="ok"
version="1.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://api.7digital.com/1.2/static/
7digitalAPI.xsd" ><artist id="473615"><name>Veronica Falls</
name><sortName>Veronica Falls</sortName><url>http://www.7digital.com/
artists/veronica-falls/?partner=1375</url><image>http://cdn.
7static.com/static/img/artistimages/00/004/736/0000473615_150.jpg</
image><bio><text></text></bio></artist></response>?

Part 2 (error) -

<?xml version="1.0"
encoding="utf-8" ?>
<response status="error" version="1.2">
<error code="9001">
<errorMessage>Unhandled 7digital API server error.</errorMessage>
</error>
</response>

We are not merging or threading any requests across our code.

Why do we receive a correct response followed directly by an error
code?

We're confused with the behaviour you're experiencing, we can't duplicate it with CURL, we don't see this behaviour with any other clients and you say you can't duplicate it outside the application.

The API doesn't set a second response so would it be possible to have the headers and any other information from the application?
