• The minting policy hash is only usable for comparison. As the script is parameterized, the actual script is unique per Head.

I'm really looking forward to find out which query is failing via the logs!

When we know, I think we can solve this at the root and change the query correctly to be not prone to some race condition!?

Marking this as request changes because we can't merge it like this because of the tracing though.

[ch1bo]

This will make our logs non-JSON and hence it can only be temporary / blocks merging of this IMO.

[v0d1ch]

So far using query at the tip works. Let's wait one more day and say this is a fix if we don't see any Retrying query logs.

[ch1bo]

Can you please rename the PR title? Change looks good!
