The IDL for program `6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P` is published and I'm guessing it's pump.fun 

I'm assuming error you are encountering is telling you that the coin no longer exists on pump.fun because the `$69k` market cap has been reached and the liquidity has been moved to Raydium and burned.
