Test is failing with error BufferedImage: type not supported: 0 --- please report this problem

Hello,
I am using RobotFramework in our virtual environment. We have installed SikuliLibrary 2.0.0 and running the tests in Pycharm CE.

We want to run a test where want to click on the play button in the web-player.
When we run the test case it fails on this error message:

Selecting a program:: Quick smoke test | FAIL |
org.sikuli.script.SikuliXception: Finder::isValid: image to search is empty
------------------------------------------------------------------------------
play episode-FirstDates:: This is some basic information about the... | FAIL |
1 critical test, 0 passed, 1 failed
1 test total, 0 passed, 1 failed
==================================

In the log I can see this specific error:

Params: [/Users/tuanminhhoang/Documents/development/robot-scripts/ui-test-automation/img/playbuttonUI.jpg]
[error] Finder2: makeMat: BufferedImage: type not supported: 0 --- please report this problem
[error] Finder: /Users/tuanminhhoang/Documents/development/robot-scripts/ui-test-automation/img/playbuttonUI.jpg: (88x72): conversion error --- find will fail

I attached the images that I want to click on in the web-player. Both are failing.

Does anyone have any tips?
