Function lacks ending return statement and return type does not include 'undefined'.

In the following async await function I had return type of Promise: <any> but I wanted to correct that so I did the following:

export const getMarkets = async (): Promise<IGetMarketsRes> => {

  try {

    const nomicsUSD = prepHeaders('USD');

    const marketUSD = await nomicsUSD.get(exchangeMarketPrices);

    const nomicsUSDC = prepHeaders('USDC');

    const marketUSDC = await nomicsUSDC.get(exchangeMarketPrices);

    const nomicsUSDT = prepHeaders('USDT');

    const marketUSDT = await nomicsUSDT.get(exchangeMarketPrices);



    console.log('marketUSD', marketUSD);



    return {

      marketUSD: marketUSD.data,

      marketUSDC: marketUSDC.data,

      marketUSDT: marketUSDT.data

    }

  } catch (err) {

    console.error(err);

  }

}

However that creates the error above.

Where getMarkets is called:

export const fetchMarketPrices = (asset: string) => (dispatch: any) => {

  dispatch(actionGetMarketPrices);

  return getMarkets().then((res) => {

    const { marketUSD, marketUSDC, marketUSDT } = res;

    const combinedExchanges = marketUSD.concat(marketUSDC).concat(marketUSDT);

    const exchangesForAsset = combinedExchanges.filter((marketAsset: IMarketAsset) =>

      marketAsset.base === asset);

    return dispatch(actionSetMarketPrices(exchangesForAsset));

  });

}

What is/are the proper Types for that Promise<> syntax?

I also tried this which I expected to be the correct way, but got a missing return for Promise, but this is an async await function which is why the return is in the try statement:

export const getMarkets = async (): Promise<IGetMarketsRes> => {
