Hi,

for that you have to extract the date from that json output. Could you show how the json output as per step 1 looks ?

EVALUATE needs to return a table. At the very minimum your query needs to be

EVALUATE { LASTDATE(bi_daily_agg_engagement[date]) }

Your date comparison should follow the ISO-8601 format.

Hi,

To get the date from json output stored in compose action - try this expression

if the compose action name is Compose, then

outputs('Compose')?[0]?['tables']?[0]?['rows']?['bi_daily_agg_engagement[date]']

But the date value which you get from the above expression should the format the utc date and also both dates should be of same timezone.

So assuming both dates are of same timezone, then it you can convert the utc date format in following expression

formatDateTime(utcNow(),'yyyy-MM-ddTHH:mm:ss')
