I don't think this is related to the task. But rather to one of your dependency.

also worth noting Yarn now comes in standard on Azure pipelines image and you may not need this task at all anymore, you can just use a script task instead.

@YarnUser31 This problem is related to node-sass and azure. Azure pipelines were updated on November 29 to Node 16 and your versions of node-sass probably is valid up to v14 Upgrade your node-sass (since May 2021 supports Node v16) or change the pipeline setting to use Node v14
