[BUG] In Rust WASM imports, the __wbg_height function expects a number but receives a string, causing a crash

[noomly]

The function __wbg_height in the Rust WASM imports expects that the value returned by rawImports.Block.height() is a number.

warp/src/core/modules/impl/wasm/rust-wasm-imports.ts

Line 710 in 25b2abd

_assertNum(ret);

When using ArLocal, the value is effectively a number, it is however not the case when using the mainnet, which in this case returns the height in a string. This causes the assertion to fail and crash the Rust contract that would try to get the current height of the tx.

To Reproduce

• Deploy a Rust contract to mainnet that makes use of Block::height()
• Publish a transaction that triggers the contract to call Block::height()
• Notice how Warp now crashes every time we try to evaluate the contract

Here is the log of the crash. The first line is from a debug log I added right before the call to _assertNum:

wasmLogger.error(`ret type: \`${typeof ret}\`; ret value: \`${JSON.stringify(ret)}\``);
