Web Object issues

I keep getting the following error when using a web object inside my Storyline module. It resides in Workday Learning.

AccessDeniedUser: arn:aws:sts::693769937420:assumed-role/dubnprd-scorm-scorm_gateway_api_task/c1303cd3ed7145228f0298fc76b38032 is not authorized to perform: s3:ListBucket on resource: "arn:aws:s3:::workday-media-eu" because no identity-based policy allows the s3:ListBucket actionNZG6K589TMHPV9FZlhYSHIH33Zf7uLdD/jhLcjxK3zj1T3wOxT5ykEOXk2ENEyGGeXvTpfMGFgZho+USIXAPWQth6UFYyXEdSIbTKcfgoDaxW+2r

Anyone knows how to fix this or what is causing this?
