this guide https://docs.scrt.network/secret-network-documentation/development/development-concepts/create-your-own-snip-20-token-on-secret-network indicates that the developer environment should be set up according to these guidelines: https://docs.scrt.network/secret-network-documentation/development/getting-started/setting-up-your-environment which help the user set up SN on a localhost. but then the SNIP-20 guide proceeds to build the contract on pulsar-3, which doesn't work

I've created an account on pulsar-3 and modified the script to use this account but am getting an error where the transaction is created but doesn't contain a .arrayLog value (it's undefined). instead, I see a .rawLog that contains something like:

signature verification failed; please verify account number (25421) and chain-id (pulsar-3): unable to verify single signer signature

and I haven't been able to figure out why this is happening. help?
