Listen Migrations : Some migration transactions don't have the 'Program data' log

[vedthemaster]

Hello,

I was using the logsubscribe method for monitoring the migrations from pump fun to pumpswap and noticed that the code is getting the transactions, but it is not able to extract the data. I put some logs and noticed that some transactions do not have the "Program data:" in the log, so it is not able to extract the information.

Hi. Please have a look:
#87

Unfortunately, it's a known limitation of that approach.

Ohh, I did not see that. I thought it was a new issue, maybe Pumpfun updated their program. I will have a look at the already created issue.

Thank you. You can close the issue now.
