The code above is the url with which I try to filter all artifacts with have value "INFORMATION".
And part of the resourceShape of one of the Artifact Type.

There is no error, HTTP Status is 200,but nothing is returned. I double check to be sure that there are Artifact with artifact Type with attribute with Attribute Data Type = _TypeText,which is my custom type. And its value is INFORMATION. And there are such. Where is my wrong?
