404 from uniswap backend when using UI to add liquidity

[anon-dev789]

Our V4 pool on Base works for the pool page but fails when adding liquidity with "Pool is missing tickSpacing" (404 from your backend).
Pool ID:
0x4965830819a7f6d799cd57917441052403219031ce8b67f292741015c54834bc
Hook:
0xf13f646e4b246f8089d45fa22f51317121e60180 (verified on Blockscout).
Tokens:
EURC/USDC, fee 3000, tickSpacing 60. Pool is initialized on-chain and the Envio indexer has it. A previous pool with identical permissions and tokens works
fine (pool 0x6474c309551b8c70f939e7042bddb5a742910f0d90e017c41b976764ce5ca88e). The request payload sends poolReference correctly but the response returns 404 with "Pool is missing tickSpacing".

Example of the error message in the uniswap UI:

Something went wrong
There was an error fetching data required for your transaction.
Request failed: ResourceNotFound: Pool is missing tickSpacing, id: 58b11128-6a0d-4266-a0c4-a879444dc5af

It now shows 'pool not found' whereas yesterday it was there. The 0x64... mentioned above is still there.

I tried releasing a new one with the same code, but that now doesn't appear in your UI either.

The new pool is 0x46aab4057235900e579863e1f848af0c7ae812898e9ac024b7151ade699fb1c9
the hook is 0xd19296e9abdc0a83e932df0cd110791eb5da8180

can you see a problem with them in the indexer logs?

I tried setting more flags correctly, and now it is indexed:

but when I try to add liquidity:

Something went wrong
There was an error fetching data required for your transaction.
Request failed: ResourceNotFound: Pool is missing tickSpacing, id: 0c478490-6133-4017-b1de-9d53aec72455

Finally! I added some liquidity with a script, and now it'll let me do it in the UI!
