facetBy with bucketGroup throws OPTIC-INVALARGS

[llinggit]

facetBy works with namedGroup now, but still throws an error with bucketGroup as below

PlanBuilder p = rowMgr.newPlanBuilder();
    PlanBuilder.ExportablePlan builtPlan =
            p.fromLiterals(numberRows)
                    .facetBy(
                            p.bucketGroup(p.xs.string("r"), p.col("r"), p.xs.integerSeq(2,4))
            );

The error msg is

Local message: failed to apply resource at rows: Bad Request. Server Message: OPTIC-INVALARGS: fn.error(null, 'OPTIC-INVALARGS', errMsg+arg); -- Invalid arguments: cannot facetBy() with invalid columns: columns() {

So we can address your issue, please include the following:

Version of MarkLogic Java Client API

See Readme.txt

Version of MarkLogic Server

See admin gui on port 8001 or run xdmp:version() in Query Console - port 8000)

Java version

Run java -version

OS and version

For MAC, run sw_vers.
For Windows, run systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
For Linux, run cat /etc/os-release and uname -r

Input: Some code to illustrate the problem, preferably in a state that can be independently reproduced on our end

Actual output: What did you observe? What errors did you see? Can you attach the logs? (Java logs, MarkLogic logs)

Expected output: What specifically did you expect to happen?

Alternatives: What else have you tried, actual/expected?

it's not a bug. Need to wrap it inside namedGroupSeq.
PlanBuilder.ExportablePlan builtPlan =
p.fromLiterals(numberRows)
.facetBy(p.namedGroupSeq(
p.bucketGroup(p.xs.string("r"), p.col("r"), p.xs.integerSeq(2,4))
));

[ehennum]

@Ling, it's surprising to me that the call needs to be wrapped. As I read it:

• bucketGroup() returns a PlanNamedGroup.
• PlanNamedGroup extends PlanNamedGroupSeq.
• So, the return value of bucketGroup() should be a valid argument for facetBy()

What am I missing?

Hi Erik, you are right. I think I shouldn't close this issue.
facetBy accepts the return value of bucketGroup and namedGroup, but when this query is sent to the server, we get SJS side error as below. Let me reopen this issue. As we have a workaround by wrapping it up with namedGroupSeq, it's ok for us to push it to the next release, right? Ajit prepares to make the release tomorrow. Do you think we should include this one in this release?
