Web sdk 1.7.9 update - invalid signature/wasm file error when setZoomJSLib

[prasanna8 (Prasanna)]

Description
I am getting this error when integrating into my web app. It used to work fine before the 1.7.9 update.
I have also tried going back to the original code. but that leads to a different net:err 403 blocked which leads to wasm file error when I setZoomJSLib as 1.7.8, so I had to update to 1.7.9
ZoomMtg.setZoomJSLib(‘https://source.zoom.us/1.7.8/lib’, ‘/av’) results in the error above.
I am using the sample ruby code given in the documentation to generate the signature for the meeting.
Getting signature invalid error and when I’m using 1.7.9 with the code I had for 1.7.8 and the page is just black after I join.
I am importing the module locally and using.

Hey @prasanna8,

Can you share your Web SDK signature to developersupport@zoom.us so I can debug?

Thanks,
Tommy

Update: Found a thread. @deepak2’s code Invalid Signature with Sample Web App helped me solve this issue.

Hi,

I also have this issue but can’t see how @prasanna8 code has resolved it?

I’m just using the CDN example from the zoom site and I get this same error? Surely it should work without recoding the signature function?

Any help would be very gratefully received.

Thanks,
Jamie

Hey @prasanna8,

Happy to hear you resolved the issue!

Thanks,

Hey @jamie.reynolds,

Please post your Web SDK signature here so I can debug.

Thanks,
Tommy

Thanks for responding. I actually realised my issue was due to having the wrong app type. JWK key fixed it.

Although I’ve had few other issues. With 1.7.9 I get the recaptcha but half the time I get a false incognito error. And if I role back to 17.8 I get issues with the browser being reported as old and not supporting audio. I’m on a mac btw.

Thanks,
Jamie

Hey @jamie.reynolds,

Checkout the solution solution to the recaptcha issue here:

Zoom Developer - Technical Documentation and Reference

You can also fill out this form to request recaptcha be not required for 1.7.9+

Hey @mohana.venu,

Please share your Web SDK signature for a test meeting so I can help debug.

Hey @tommy,

I am also facing the same issue. I have purchased a Pro plan on Zoom but I am still getting the invalid Signature error

My Meeting Signature

[dinesh.patil (Dinesh)]

@tommy I am also getting the same error as mohana. I am trying with the sample-web-app and using websdk keys. Here is my signature which I copied from my browser console.

[tommy (Tommy Gaessler)]

Hey @dinesh.patil,

You are using SDK App Credentials, you need to use JWT App Credentials.

Thanks,
Tommy

[tommy (Tommy Gaessler)]

Hey @ashwin.parihar, @mohana.venu,

Your signatures look correct, however, It appears you are trying to start meetings (passing in role 1) you do not own.

The Web SDK can only start meetings owned by the same Zoom org account that owns the JWT App.

Thanks,
Tommy

[dinesh.patil (Dinesh)]

@tommy, I have already tried that. But in that case I get API key length error.

[ashwin.parihar (Ashwin)]

Hey @tommy,

I have a SaaS app, which allows ours users to create a Zoom Meeting after oAuth Login, neither they know how to create a JWT app, nor I can ask them to create one.

Tell me how can my users start their Zoom Meeting (WebSDK) from my web app, after oAuth Login.

[tommy (Tommy Gaessler)]

Hey @dinesh.patil,

What version of the Web SDK are you using? Please try using version 1.7.10 and your JWT App. If you are still having issues, please create a new topic and fill out the post template so we have enough info to help.

Thanks,
Tommy

Hey @ashwin.parihar,

Please see my post here:

Start a meeting on behalf of a user - Web SDK with OAuth

Hey @mayank.patel, We discourage asking customers to share their JWT Credentials with developers. I do see the headache here how you can’t use OAuth to start meetings for a user via the Web SDK since the Web SDK can only start meetings owned by the same account as the JWT App. I will share this feedback with our team and see if we can expand the Web SDK authentication to allow authorized users to start their own meetings. (CS-2206) In the meantime, I suggest having the host of the meeting s…
