After upgrading to the latest Web SDK version 2.18.0 we are getting the “Fail to join meeting”. Upon inspecting the console we can see an “Inavlid Sdk key” error however we are using the same SDK key that was working on previous versions. { “method”: “join”, “status”: false, “result”: “Invalid sdkkey.”, “errorMessage”: “Fail to join the meeting.”, “errorCode”: 1 } **How to reproduce the issue** Occurs after clicking the join button **Which Web Meeting SDK version?** 2.18.0 **Meeting SDK Code Snippets** ZoomMtg.init({ leaveUrl: meetingConfig.leaveUrl, webEndpoint: meetingConfig.webEndpoint, disableCORP: !window.crossOriginIsolated, // default true // disablePreview: false, // default false externalLinkPage: ‘./externalLinkPage.html’, success: function () { console.log(meetingConfig); console.log(“signature”, signature); ZoomMtg.i18n.load(meetingConfig.lang); ZoomMtg.i18n.reload(meetingConfig.lang); ZoomMtg.join({ meetingNumber: meetingConfig.meetingNumber, userName: meetingConfig.userName, signature: signature, sdkKey: “REDACTED”, userEmail: meetingConfig.userEmail, passWord: meetingConfig.passWord, success: function (res) { console.log(“join meeting success”); console.log(“get attendeelist”); ZoomMtg.getAttendeeslist({}); ZoomMtg.getCurrentUser({ success: function (res) { console.log(“success getCurrentUser”, res.result.currentUser); }, }); }, error: function (res) { console.log(res); }, }); }, error: function (res) { console.log(res); }, }); **Device (please complete the following information):** Reproduced on Windows 11 Google Chrome ---

Can you please make sure that the signature generated is valid? > **[Troubleshooting Meeting SDK signature validation](https://developers.zoom.us/blog/troubleshooting-meeting-sdk-signature-validation/)** > > placeholder description ---

The signature generated should be valid. The SDK app contains all the relevant fields and is active on the Zoom App marketplace. This is the signature that is being generated: REDACTED ---

Hi @management Sorry about that, I did not get a notification about your message. By any chance, are you using React in your app? we found an issue where our meeting sdk for web 2.18 does not work with react 18. If this is your case, can you please downgrade to react 16? And please tag me when you reply so I get a notification ---

@elisa.zoom we are not using React. We are actually using the zoom meeting sdk web sample app which we have embedded into an [asp.net](http://asp.net) page. ---

If you run this sample app, you get the invalid signature error too? ---

That’s correct @elisa.zoom. We have hardcoded the sdk secret and key in the sample app. Is there a way to verify if the sdk key is valid? ---

I do not have a way to verify it @management Can try and run the sample app with the same key and secret you are using? If not, can you try and run the sample app with a new set of credentials? you can create a new meeting SDK app for testing purposes
