Project 9 - TypeError: Cannot read properties of null (reading 'gatewayUri')

[tuncatunc]

Hi All Solana Bootcamp 2024 participants.

I made to Project 9 and it's complex and there are much reward for those who're patient.

when building sb commit ix, it throws gatewayUri error.

Anyone has this problem?

Thank you!

PS: run setup and start validator script a few minutes ago.

I have same essue. how to fix it?

[tuncatunc]

No solution however there's a clue.
There's loop in the sb source code, it iterates over loaded oracles however oracles doesn't have gateway uri field and it throws error.
May be the setup.sh script iş loading wrong oracle addresses.

facing same error. have any body found solution?

[TemiW3]

facing the same issue here, have not been able to find the solution

There is a solutions for this issue. Just test it on Project 9, Solana StackExchange
