EconomyAPI Not Compatiable With Plugin

I am trying to use a plugin and getting errors, I think cause its a little old and maybe the plugin code is calling to an older function and needs to be changed?
ERROR

Code:

Call to undefined method onebone\economyapi\EconomyAPI::getConfigurationValue()

Plugin Code

Code:

  $autoSaveTerm = EconomyAPI::getInstance()->getConfigurationValue("auto-save-interval");

 

how would I run such a command to get output and see if it is null or not?

this seems to be whats in EconomyApi.php

Code:

if($this->getConfig()->get("auto-save-interval") > 0){
$this->getServer()->getScheduler()->scheduleDelayedRepeatingTask(new SaveTask($this), $this->getConfig()->get("auto-save-interval") * 1200, $this->getConfig()->get("auto-save-interval") * 1200);
}

 

I was looking through console and noticed there is a little more to the error.

ERROR 1;

Code:

Call to undefined method onebone\economyapi\EconomyAPI::getConfigurationValue()" (EXCEPTION) in "/EconomyPotionShop.phar/src/Khinenw/PotionDispenser/Dispenser" at line 97

ERROR 2;

Code:

[Server] INFO Notice: Use of undefined constant EconomyAPI - assumed 'EconomyAPI' in phar:///plugins/EconomyPotionShop.phar/src/Khinenw/PotionDispenser/Dispenser.php on line 63

Update;
I just checked I have a ton of plugins that use

Code:

use onebone\economyapi\EconomyAPI;

although I dont see them using "::getConfigurationValue()" so maybe the call to the plugin is incorrect?
I am attempting to use This Plugin

UDATE2;
it is definitly not using the right function, I can only find "getConfigurationValue" in an older version of EconomyAPI that I have "EconomyAPI v2.0.9" none of the new files contain this function.

 

updating the plugin to the new config function for economyAPI fixed it thanks.
