This questions has been raised a number of times and I still do not have found an answer.
Embedded report is not opening anymore when switching to Splunk Free.
From the feature comparison table https://www.splunk.com/en_us/products/splunk-enterprise/free-vs-enterprise.html
its not clear whether this should be supported or not.
Please also check this.
Can someone give an adequate answer is this a glitch or this feature is not supported in Splunk Free?
I am afraid embedded reports are not a part of Splunk Free license. Here are the list of features compared -
Embedded Reports Embed charts and reports in other third-party business applications external to Splunk Enterprise
Splunk Free N
Splunk Enterprise Y
Splunk Cloud Y
