When querying the Content Service on SDL 8.5, we keep getting "`?' expected but `C' found"

Question

When querying a fresh install of SDL 8.5 Content Delivery content service at http://example.com:8081/client/v4/content.svc/Components(ItemId=13,PublicationId=3) we keep getting the following error:

<metadata:error>
    <metadata:code>1000</metadata:code><metadata:message>`?' expected but `C' found</metadata:message>
</metadata:error>

And this is what we get in the cd_core.log:

The services installed are: discovery deployer deployer-worker content

All were started with the --auto-register flag and they all registered successfully with the discovery service. They're running on a UNIX box

Answer 1

Issue looks to have been resolved after updating cd_storage_config.xml file and republishing publication to the broker DB.

Answer 2

I recently ran into this same issue on a web 9.1 install. Our issue was that our cd_storage_conf.xml for our deployer and our content service was out of sync. In the deployer we had our config publishing some items to the file system and others to the broker. However, in our content service, we did not have any item types pointing to the file system. Syncing the two cd_storage_conf files fixed this for us.

Note: while fixing it we also found that the issue could occur if your content service's storage_conf.xml file was malformed in any way. We ran into this when we incorrectly nested two tags directly inside each other.

We also saw this issue with XPM enabled if we were reaching out to a non-session enabled content service. Enabling session preview on the content service fixed this.
