Invalid Value Type In yarn.lock?

I am fairly new to web development - very new to npm and yarn. I am at the end of a web developer bootcamp and trying to make my final project live on the web. Render was the suggested platform for this.

I utilized the Node.js instructions. Took the original template and updated with my code. Confirmed working on my machine (installed required npm packages) and confirmed merge working. When I pushed to the branch for auto deploy, was given the following:

resolved by deleting the yarn.lock file and re-running yarn install --check-files
