Solana Test Validator Error Log Incorrect

[leofisG]

Problem

The Solana test validator have a strange issue where waiting causes test to fail.

You can see a Proof of Concept here.

As you can see, the test is working in the main branch. The only change that I have made is that I added the line:

    await sleep(500) // This causes the error

The error message is the following:

Transaction simulation failed: Error processing Instruction 2: invalid account data for instruction 
    Program Port7uDYB3wk6GJAw4KT1WpTeMtSu9bTcChBHkX2LfR invoke [1]

    Program Port7uDYB3wk6GJAw4KT1WpTeMtSu9bTcChBHkX2LfR failed: invalid account data for instruction

You can see the complete error log here.

The error is related to a Token Program error. However, all the account that gets passed in is the same with the same set up except for just adding one line of sleep. We suspect the actual failure is not as displayed by the error, but instead it is because of the fake oracle time slot is too late. However, this is not correctly displayed in the test validator and causes a lot of confusion.

Proposed Solution

We hope that the Solana team can look into it and find the root cause.
