Inter contract call throws Revert(123)

Cross referenced with the sway issue

One of our ecosystem projects is reporting problems when trying to create a dApp where the contract includes an inter contract call to another contract.

The error suggests its a mismatched selector, however certain functions from the same contract, with the same ABI work successfully.

I've created a minimal reproduction that demonstrates this behaviour in both TS and RS. However, it has been reported that the RS test does work successfully locally, currently I have it running against testnet.

First step would be to port the RS test to local to get it working successfully, then we can compare what is happening between the 2 SDKs.

@petertonysmith94 diligently spotted that upon upgrading Pyth to the latest versions of forc@0.62.0 and fuel-core@0.31.0 and the SDK 0.92.1, this problem was resolved. I think the main culprit was this Sway change. We've gone back and fourth with them over version changes, this has consistently been the reason for problems and we have not had to make any changes to the SDK, no bugs have been found.

I've also offered a new working reproduction and integrated local TS testing with their own exemplar repository to better support them.

Closing this issue as this is not a problem with the SDK.
