delegate inscription content not displayed

[DeeList]

The following inscriptions fail to appear in Leather:

https://ordinals.hiro.so/inscription/a77c2fda458fc67028cb444b3b3fdcdf36b168d89ceb7286630d2fc76b21a714i476 https://ordinals.hiro.so/inscription/fc7e21fc4e8140100f5913a0e0d6ce1675b73298ba97de65ef0130169369f3dci421

The /ordinals/v1/inscriptions/:id/content endpoint is not returning any data for some inscriptions.

Not even throwing an error, just returning an empty response. example

Could this be related to not supporting unknown and/or HTML mime types?

Edit:

Using the "genesis-ID" way seems to work while sat number doesn't.

More complicated inscriptions (which I assume have things like parent inscriptions) still don't work.

It feels like it is could be related to this, but I can't see any problem in the code.

Transferring to ordhook. I have confirmed the content for some locations is not being sent correctly via predicates, for example (note content_bytes and content_length):

{
  "inscription_revealed": {
    "content_bytes": "0x",
    "content_length": 0,
    "content_type": "image/png",
    "curse_type": "Generic",

This is really an API bug, we should be displaying the content of the delegate inscription.

EDIT: Ordhook provides this and other missing fields as

metaprotocol
inscription_pointer
inscription_output_value
inscription_input_index
delegate
