Yarn webiny deploy error



I have installed everything locally following instructions. First deployment ran correctly without any issues.

However, after working for a while on the website, modified theme, added category and a new page, I tried to run deploy again but it fails with the following error:

 $ yarn webiny deploy
yarn run v1.16.0
$ '/net-webiny/node_modules/.bin/webiny' deploy

I am stuck and no idea how to move forward. Please give me some directions on how to resolve or investigate the problem.
