I had an error with this code
exports.getResults = (req, res) => {
status = await miDealApi.getResults()
res.json({
status: status
})
}
The issue was that i used 'await' without declaring the method as 'async', but the error Node.js was giving me was very unclear, and didn't help me figuring it out at all.
internal/modules/cjs/loader.js:999
throw err;

Is there anything i can do to make errors like this clearer in the future?
One possibility is that your node.js version is a bit older, and thus, doesn't give you the proper error.
Running with Node 12 I get:
/project/foo.js:2
status = await miDealApi.getResults()
^^^^^

So you might want to check your version?
node -v
12.21.0
You should always aim for working with at least the stable version.
Keep in mind: await has to use with async.
An async function is a function declared with the
asynckeyword, and theawaitkeyword is permitted within them. Theasyncandawaitkeywords enable asynchronous, promise-based behavior to be written in a cleaner style, avoiding the need to explicitly configure promise chains.
Change your code like below:
exports.getResults = async (req, res) => {
status = await miDealApi.getResults()
res.json({
status: status
})
}
Happy coding :)
