Forced to join a project which is in Drupal UI

Hello everyone, I am a Angular developer with exp of 2+ years and recently I have being moved to a different account(MFG Nag). Here in the past 1 month they are trying to assign me a project as a angular dev, but due to client delays it got stuck. Now the delivery partner is giving me a different project which is completely different from the skills I have. It is based on Drupal and if I join my angular skills will be of no use. The tickets is mostly of html css jquery. What you you do in this situation.
