bug: Provided Gas for Axelar is insufficient #861

[mustermeiszer]

This is an estimation bug from the SDK side. The provide value is insufficient to satisfy the onchain gas calculations.

• Failing sim here - fails at Axelar at the end
• Happens in prod and on manage-demo branch

sdk/src/Centrifuge.ts

Lines 670 to 704 in 21b4e11

	repayBatch(fromCentrifugeId: number, toCentrifugeId: number, batch: HexString, extraPayment = 0n) {
	const self = this
	return this._transact(async function* (ctx) {
	const [addresses, client] = await Promise.all([
	self._protocolAddresses(fromCentrifugeId),
	self.getClient(fromCentrifugeId),
	])
	const batchHash = keccak256(batch)
	const [counter, gasLimit] = await client.readContract({
	address: addresses.gateway,
	abi: ABI.Gateway,
	functionName: 'underpaid',
	args: [toCentrifugeId, batchHash],
	})
	if (counter === 0n) {
	throw new Error(`Batch is not underpaid and can't be repaid. Batch hash: "${batchHash}"`)
	}
	const estimate = await client.readContract({
	address: addresses.multiAdapter,
	abi: ABI.MultiAdapter,
	functionName: 'estimate',
	args: [toCentrifugeId, batch, gasLimit],
	})
	yield* doTransaction('Repay', ctx, () =>
	ctx.walletClient.writeContract({
	address: addresses.gateway,
	abi: ABI.Gateway,
	functionName: 'repay',
	args: [toCentrifugeId, batch, ctx.signingAddress],
	value: estimate + extraPayment,
	})
	)
	}, fromCentrifugeId)
	}

This method does not caculate the gas correctly. Use in the scanner to repay but creates a tx with insufficient gas - see here

Lets clarify on whether from and to are swapped.
