Hi @almira, 

Thank you for writing this post! 

I understand you are making a Dashboard API call, but got the 400 error. Usually this error means something is this request is not correct. I can see all the types in your request is “event”, can you check if all the properties you queried in the chart are event properties? How many days are you querying in the chart? 

Best,

Hi @Amplitude Admin Thanks for replying

Ya i forgot to include the date (start & end) and the days.

But is there any possibility in the future to update the error message so we have clear message what is missing or not correct. I think it would be helpful.

BR,

Almira
