Why this error occurs in automation chain when use Query operation?

I have a content view and it has defined a nxql query, it works perfectly. Now I want to get those documents using query operation in a automation chain for create relations with another documents but an error is printed in the server log.

My automation chain:

> Context.FetchDocument:run

> Context.SetInputAsVar:run
name: tramiteFolder

> Context.SetVar:run
name: variableContext
value: @{Document["myschema:myfield"]}

> Document.Query:run
query: SELECT * FROM Document WHERE anotherschema:anotherfield = '@{variableContext}' AND ecm:currentLifeCycleState != 'deleted'

> Relations.CreateRelation:run
object: @{Context["tramiteFolder"]}
predicate: http://purl.org/dc/terms/References

This is my logic:

  1. I have a workflow, it is started automaticaly when document type “A” is created
  2. I want to run my chain on automatic_transition from start node.

the error printed in the log:

on the other hand, I have another chain where I create this same logic and works perfectly but with another query:

SELECT * FROM MyTypeDocument WHERE uid:uid = '@{variableContext}'

ANSWER

Why are you using @{code} in the query ? Are you using the context object.

The strange is that the creation behave as that can't accept a documentmodelList. That's why when your query return just one result it works. Can you give your Nuxeo instance version and hot fixes applied ?

Hi, I updated my example code in my question, "code" is a context variable. I replaced "code" by variableContext. But is strange because the operation create relations should accept documentModelList. My nuxeo instance is 5.6 and hotfixs from 1 to 16

Hi,

The reason of your problem is that create Relation expects a Document as a value for parameter “Object”, and you give a document list (tramiteFolder).

Indeed, the input of the chain is a document list. So, Context.SetInputAsVar sets a documents list as a variable.

You could simply refer to “@{workflowDocuments[0]}” in the object attribute, or, just before Context.SetInputAsVar, use a Run Script operation with “return This[0]” script value.
