Qlik Predict - Forecast Real-time Prediction Failed Precondition Error

Hi everyone,

I hope you are all doing well. I am writing to you all mainly because we are getting an error while using the real-time API function in Qlik Predict, specifically the FAILED_PRECONDITION error when trying to load the data for a forecast app. Additionally, we kept the Enable real-time API access option active in the experiment when we deployed it.

On the other hand, this is current script.

ForecastData:

LOAD

'Real' as Type,

Date,

MonthName(Date) as YearMonth,

TotalSales

FROM [lib://ML-Lab:DataFiles/ML/DataViz/training-sales-union.qvd]

(qvd);

[ML Predictions]:

Load

EXTENSION endpoints.ScriptEval('{"RequestType":"endpoint", "endpoint":{"connectionname":"SBX GE2_BEFLOW:TestConnection"}}', ForecastData);

Last but not least, this is the error we are getting after we try to load the data:

We are looking to hearing from you soon!

Thanks a bunch!

No answer?

I have the same problem whith new deploys, whereas old deployments keep on working.

It happens after a message about update problems at tenant level

Hello @Oslo_Qlik

So far, no answer. We keep getting the same error but only when the deployment is a forecast. We have it with a regression model and it works perfectly fine. Moreover, we tried today and still, the same error is displayed.

Thanks!
