Generic error when creating custom chart

[Vaito]

I'm running a trial of the FortiAnalyzer VM and I am not able to create custom charts. When I try to use the Chart Builder to save a chart from either Log View or Custom View, I get a pink "not pass" banner error. I've experimented with several variables without success and am not sure how to proceed without a more detailed error message.

Is this a limitation of the trial license, or am I doing something wrong? Thanks.

Thank you for the recommendation, but I get plenty of records in Log View and Custom View. I am not able to convert the queries into a chart, however.

I'm getting the same after upgrading FAZ to 7.4.2

Do you have a licensed FortiAnalyzer instance? If so, I'm curious to see what TAC has to say. For my part, I gave up on the POC and have leveraged Graylog to get the insights we need.
