Error on shopify dev with no error message in terminal

Hi

I am working on a shopify theme and while running it on my dev environment, suddenly I cant access the themes customize page, I get the message in the screenshot below. My liquid template code looks fine, also the json schema looks correct. I also dont get any error message on my terminal. Any idea what could be the possible problem?

Hello,

Thank you. I already fixed the issue. While my schema json was well formed, the issue was with the inputs in the settings and I was able to get everything working once I fixed that.
