[conorsch]

Describe the bug
Multiple DEX frontends are throwing errors in the browser.

To Reproduce
Steps to reproduce the behavior:

1. run veil dev env
2. navigate to explore page at http://localhost:3000/explore
3. observe error

Expected behavior
Page loads fine, assets render.

Screenshots
Here's the exact error text:

 ○ Compiling /explore ...

  106 |             if (metadata) { {
  digest: '3529525386'

Additional context

The error seems specific to the /explore route to me; I can load these URLs fine:

• http://localhost:3000/portfolio
• http://localhost:3000/tournament
• http://localhost:3000/trade/UM/USDC

Add any other context about the problem here.

We've merged a slightly nicer error message in Veil on the /explore route, but the problem remains: there are NaN values in the dex_aggreggate_summary table. Currently debugging that data problem.
