Bug: Missing Parameter Causes Deployment Failure

The deployCapTable function now requires a fourth issuer parameter. Existing callers, such as the /issuer/create-fairmint-reflection route, were not updated and still pass only three arguments. When a Canton chain ID is used, the issuer parameter is undefined, causing deployCapTableCanton to throw a TypeError when attempting to access issuer.legal_name. This prevents cap-table deployment and breaks issuer creation on Canton networks.

	async function deployCapTable(issuerId, initial_shares_authorized, chainId, issuer) {
	if (isCantonChainId(chainId)) {
	return deployCapTableCanton(issuerId, initial_shares_authorized, chainId, issuer);
	}
	// Get provider for specified chain
	const wallet = await getWallet(chainId);
	console.log("🗽 | Wallet address: ", wallet.address);

Bug: Canton Chain ID Handling Regression

The getContractInstance() function now returns null for Canton chain IDs. Existing read-only routes (e.g., /stockClass/id/:id, /stakeholder/id/:id) unconditionally use req.contract without null-checking, causing "Cannot read properties of null" errors when attempting to invoke contract methods. This regression breaks these previously working endpoints for Canton issuers.

open-captable-protocol/src/chain-operations/getContractInstances.js

Lines 17 to 23 in 65c5d1a

	export const getContractInstance = (address, chainId) => {
	if (isCantonChainId(chainId)) {
	console.log(`Canton chain ${chainId} contract instance is not supported yet`);
	return null;
	}
