SystemCacheClear() throws error "Reduced views don't contain document ids"

Lucee Extensions Lucee Couchbase Extension
1

I have declared that all my caches go to couchbase in application.cfc

THIS.cache.object = “cbluceestore”;
THIS.cache.template = “cbluceestore”;
THIS.cache.query = “cbluceestore”;
THIS.cache.resource = “cbluceestore”;
THIS.cache.function = “cbluceestore”;
THIS.cache.include = “cbluceestore”;

I then proceed to cache a query which I can see in couchbase as the only document in that bucket.

I then attempt to use

SystemCacheClear();

I would assume that that would clear the cached query. Instead I get:

Lucee 4.5.3.018 Error (java.lang.UnsupportedOperationException)

It seems that all of the lucee cache functions are throwing that same error. The first view in couchbase for the cache bucket has a reduce function. If I remove _reduce from the view then cache functions begin to work properly.

ie CacheGetAllIds("",“cbluceestore”)

How can I define which view the extension is to use when connecting to CB?

I also noticed this error in tomcat when the app starts:

2016-08-09 10:10:11.552 INFO com.couchbase.client.CouchbaseClient: viewmode property isn’t defined. Setting viewmode to production mode

It seems to me that there are additional settings that are not in the lucee admin / couchbase extension.

Hi Marc,

I believe we have a screenshare with you on Thursday. We will address these issues. Please note that the SystemCacheClear() requires the name of the cache as an argument. Did you pass it?

*> **How can I define which view the extension is to use when connecting to

You can't, the extension creates the view it needs automatically. Can you
confirm if there is a view named "*LuceeCouchbase_allKeys*"? That is the
name of the view that is used and it should not have a reduce function.
Did you by chance manually edit this view and add a reduce function?

I also noticed this error in tomcat when the app starts:

That is not an error. You can see from the log entry, it is marked "INFO"
which means it's informational. It doesn't not represent anything
significant.

Thanks!
