How do we deal with error handling with the subscription? Doesn't seem to ever return an error for me when I attempt edge cases that should fail (end < start, invalid topicID, etc...)

Is there a comprehensive tutorial set up that gives an intro to Hedera and then also teaches newbs in a linear format? Perhaps an option for private tutoring for interested parties? My objective is to be educated enough to know which area I want to apply this amazing technological option. Thank you kindly

I'm just beginning my journey with Hedera. Where should a novice programmer begin? My current level of programming is self taught python. Kindly outline the next steps.

Did you ever figure out why the 10th message was never retrieved at the end of the tutorial. I saw it on your face Lol you realized it. If you can provide an explanation it'd be great. If I publish 10 messages to a mosquito broker topic I expect 10 messages to be received by all subscribers, not 9.

to the developer
your token is great but your tutorials and links are extremely bad we have been trying to follow your instruction but to no avail .
- your written instruciton to create a token explain one thing while your tutorial video is saying something else
we have been sitting on this for no of days and errors are cropping up every where
if creating tokens is not user friendly your token price will not increase
while solona has a much easier format done
I could suggest all the codes are written so that we can see the end result of the whole codes erc 20 or solana using GUI so changes can be doen as per individula requiremnet
