Error with Global Variable Interpolation in Kedro OmegaConfigLoader

good morning all!
We are facing an error in using global variable interpolation with the OmegaConfigLoader. The error occurs when lunching a jupyter notebook e.g with kedro jupyter lab
the issue seems very similar/identical to the one signaled here https://kedro-org.slack.com/archives/C03RKP2LW64/p1726216824633969

the full error stack is below. The global var is located in conf\globals.yml The issue also occurs for the location conf\base\globals.yml


Any help from the kedro team is very much appreciated
