Orion expects the Context Entity and its attributes to exist, by having been previously added by an APPEND or registerContext request, when using UPDATE.
We just recently changed our examples and code to use APPEND instead of UPDATE as we also hit this error.
So the latest version (0.1.2-SNAPSHOT from master branch) examples and code should work fine with Orion.
Strangely, orion returns http status 200, even though the content indicates, that the request failed.
This is expected from Orion as this behavior is specified as part of the NGSI v1 protocol specification. All NGSI requests will always return 200 Ok HTTP response code, applications are expected to check for errorCode and statusCode tags in the response.
What is unexpected is the orionError tag which are not part of the NGSI v1 specification.
Can you confirm you still get the error once you use UPDATE with an existing Context Entity, I tried to reproduce with Postman on orion.lab.fiware.org:1026 but got no error:
POST /ngsi10/updateContext HTTP/1.1
Host: orion.lab.fiware.org:1026

response :

<statusCode>
<code>200</code>
<reasonPhrase>OK</reasonPhrase>
</statusCode>
</contextElementResponse>
</contextResponseList>
</updateContextResponse>If the Context Entity Floor3 does not exist when using UPDATE this is what is answerd by Orion:
<updateContextResponse>
<contextResponseList>
<contextElementResponse>
<contextElement>
<entityId type="Floor" isPattern="false">
<id>Floor3</id>
</entityId>
<contextAttributeList>
<contextAttribute>

<type>double</type>
<contextValue></contextValue>
</contextAttribute>
</contextAttributeList>
</contextElement>
<statusCode>
<code>404</code>
<reasonPhrase>No context element found</reasonPhrase>
<details>Floor3</details>
</statusCode>
</contextElementResponse>
</contextResponseList>

Hi Mark. Thanks for the hint with the UPDATE/APPEND. With the latest cepheus we see it working now. Also thanks for the hint reg. http status 200/400. Regarding the orion Error tag, we just opened an issue reg. that: telefonicaid/fiware-orion#1500
