Its quite possible I have a logical error somewhere but I'll ask the question anyway as I am experiencing some very weird errors..
Is it possible for web3.sendAndConfirmTransaction(..
to return a signature but moments later (for that same invocation) to throw an exception even though my program has moved onto the next lines of code..
const createMintSig = await web3.sendAndConfirmTransaction(connection, transaction, [this.appTreasPair, mintAccount], {
skipPreflight: skipPreflight
});
