Hi,
I'm trying to query a mongoDb, using the following data service.
<data name="testMongoService">
<config id="capedev-mongo">
<property name="mongoDB_servers">172.17.0.4:27017</property>
<property name="mongoDB_database">*TestDB*</property>
<property name="mongoDB_write_concern">NONE</property>
<property name="mongoDB_read_preference">PRIMARY</property>
<property name="mongoDB_autoConnectRetry">true</property>
</config>
<query id="mongo_find" useConfig="capedev-mongo">
<expression>*db.TestCollection.findOne()*</expression>
</query>
<operation name="mongo_find">
<description>mongo find operation</description>
<call-query href="mongo_find"/>
</operation>
<resource method="GET" path="test">
<call-query href="mongo_find"/>
</resource>
</data>
I can't get data from this service, it fails with the following error
message. However I can execute the same expression on the mongo db browser
I'm using because I've created the TestDB database and the TestCollection
collection.
