# X_INVARIANT_VIOLATED

## Means

a domain invariant rejected this row

## Typical cause

a CHECK or a declared invariant failed. This page printed `x entity explain` until 1.2.0; the registry command is plural and its subcommands are `list` and `show`

## Fix

`x entities show <entity> --json` — every invariant with its `kind`, `message`, `sql` and `where`
