Campaign ROI doesn't work on 7.5.3 but works on 7.4

Hi guys,

making a testing lab, I discovered that when I add a Dashlet “Campaign ROI” chart on HOME, it does not shows anything based on suitecrm 7.5.3, however if I go to 7.4 and make same testing lab, it shows.

Error in apache logs:
/* When adding the dashlet */

/* Finish log when adding dashlet*/

Then, after editing and configuring with the pencil icon and select the campaign and configure auto refresh time:
