    Hi weiyu_chen ，

    I checked some of the relevant restrictions and it seems that none of them are touched on your side...

    1. Only 1 DAX query can be executed per REST API request.
    2. Each DAX query can have only 1 result set.
    3. Result sets are capped at 100k rows.
    4. Supported data types: string, numeric, boolean, blank, datetime and variant. Binary is not supported.
    5. Azure AS and SSAS do not support this DAX REST API.

    Is it possible that the error is reported because this DAX Query returned a single value, but the required return result here is a table? Change the DAX Query to the following form and see if it works:

    {
"query": "EVALUATE SUMMARIZE (
    'Activity',
    \"countofpriority\", COUNTAX ( FILTER ( 'Activity', [Activity Status] = \"Completed\" ), [Priority] )
)"
}

    Best Regards

Thanks for the reply. I have tried your suggestion, get the following error:

{
"error": {
"code": "BadRequest",
"message": "Bad Request",
"details": [
{
"message": "After parsing a value an unexpected character was encountered: \". Path 'queries[0].query', line 3, position 69.",
"target": "request.queries[0].query"
},
{
"message": "'request' is a required parameter",
"target": "request"
}
]
}
}
 
The query body is:
{
"queries": [
{"query": "EVALUATE COUNTAX(FILTER('Activity',[Activity Status]=""Completed""), [Priority])"
}
],
"serializerSettings": {
"includeNulls": true
}
}
 
Thanks!
