Transaction Confirmed but failing with overflow

[pascaloberle]

Hi all and thanks for the great code and support!
I just see my transactions are confirmed
.... Bonding curve address: 6DLfCj6LjwLG3sCrHV3BYtNtrvGRMrLGoM5ny6arsaFB Token price: 0.0003334000 SOL Buying 0.010000 SOL worth of the new token with 35.0% slippage tolerance...

But if you inspect all my attempts (with and without set compute unit price it keeps failing)

#1 Pump.fun instruction

Program log: Instruction: Buy
Program log: panicked at programs/pump/src/lib.rs:615:48: attempt to subtract with overflow
Program Pump.fun consumed 18864 of 200000 compute units
Program returned error: SBF program panicked

I am not sure if I can be missing anything from the instructions
{
amount:{
type: "u64"
data:"29994001"
}
maxSolCost:{
type:"u64"
data:"13500000"
}
}

From the code below in the transaction
data = discriminator + struct.pack("<Q", int(token_amount * 10**6)) + struct.pack("<Q", max_amount_lamports) ?

are you able to derive a bit more what the token_amount * 10**6 is supposed to represent? is it just the amount of token to buy offset to million for some reasons? I just suspect (just a guess at this stage) that there could be some problem with the amount but not too sure
