Keep Getting Promise { } When Returning Current Version of Extension and Latest Version in Hub

Hi all,

I'm currently working on a Code dashboard tile which shows the current version of an extension in relation to the latest version posted in the hub. I'm hoping to use this code for Workflows so I can be notified when extensions fall out of date. But I need to get over this first hurdle.

This is the code I have created so far:

async function checkVersion(extensionName) { // fetching extensions from the hub const response = await fetch( 'https://{environmentid}.live.dynatrace.com/api/v2/hub/extensions2/' + extensionName, { headers: { method: "GET", Accept: "application/json; charset=utf-8", 'Authorization': 'Api-Token <REDACTED>' } } ); const result = await response.json(); return result.extension2Details.recommendedCatalogVersion; } export default async function () { // fetching current extensions in environment const response = await fetch( 'https://{environmentid}.live.dynatrace.com/api/v2/extensions', { headers: { method: "GET", Accept: "application/json", 'Authorization': 'Api-Token <REDACTED>' } } ); const result = await response.json(); const itemsArray = Object.values(result.extensions); const filteredItems = itemsArray.map(extension => ({ 'Extension Name': extension.extensionName, 'Version': extension.version, 'Version To Date': checkVersion(extension.extensionName).then() })); //console.log(checkVersion("com.dynatrace.filesystem").then()); return filteredItems; }

I realise this may be an issue with items not being resolved yet as part of the checkVersion() function but even manually calling it makes this appear in the console:

Promise { <pending> }

..which I assume is happening in the table generated from this, too.

If I use await like this:

await checkVersion("com.dynatrace.filesystem")

…I do get some data back, but I can't use it in the mapping function as I get this:

"message": "Parse error: await isn't allowed in non-async function at file:///script.ts:34:30\n\n 'Version To Date': await checkVersion(extension.extensionName)

Hi badgerfifteen,

As the error message indicates, you must be in an asynchronous function to use the "await" prefix. This prefix is necessary to wait for the promise to resolve before proceeding to the next step. Currently, your function is asynchronous, but the mapping is not:

const filteredItems = itemsArray.map(extension => ({ // No async prefix here 'Extension Name': extension.extensionName, 'Version': extension.version, 'Version To Date': checkVersion(extension.extensionName).then() // Need to be proceed before }));

You need to have something like that :

itemsArray.map(async (extension) => ({ ... })

To fix this, you can do :

async function checkVersion(extensionName) { // fetching extensions from the hub const response = await fetch( 'https://{environmentid}.live.dynatrace.com/api/v2/hub/extensions2/' + extensionName, { headers: { method: "GET", Accept: "application/json; charset=utf-8", 'Authorization': 'Api-Token <REDACTED>' } } ); const result = await response.json(); return result.extension2Details.recommendedCatalogVersion; } export default async function () { // fetching current extensions in environment const response = await fetch( 'https://{environmentid}.live.dynatrace.com/api/v2/extensions', { headers: { method: "GET", Accept: "application/json", 'Authorization': 'Api-Token <REDACTED>' } } ); const result = await response.json(); const itemsArray = Object.values(result.extensions); // Use Promise.all to handle asynchronous operations const filteredItems = await Promise.all(itemsArray.map(async (extension) => { const versionToDate = await checkVersion(extension.extensionName); return { 'Extension Name': extension.extensionName, 'Version': extension.version, 'Version To Date': versionToDate }; })); return filteredItems; }

Let me know if it fix your problem

Have a nice day,

Sincerely
