The next available para-id = 4290

para-id 4290 is showing in Overview but lighter shade (lost in space?)

this is not a new issue (have seen it reported in Jun 2022.

how do we proceed? thank you

  • The para-id 4290 is registered as a parachain, I am going to investigate why the next available para-id is still 4290. Where did you see it reported the last time it happen?

The reason for that has to be some forced sudo operation, otherwise that is not a possible state.

Thanks for flagging this, it has now been addressed.

In respect to

My understanding is that polkadot-js/apps greys out parachains that are not producing blocks or their nodes are not reachable.


thank you but i don't think it has been resolved. i am trying to request for a para-id and 4290 is showing up but when i tried to register it, it says it has been registered and it doesn't go through.

same problem as below : "registrar.AlreadyRegistered "

Provided next available para id is already registered
