I just installed the SDK following the process described at https://marketplace.zoom.us/docs/sdk/native-sdks/web
I also get the error: “Api key length error, must 22”
This looks like it was written by someone who does not speak English well and was written when your API key character limit was 22 characters.
My API Key is 36 characters in length.
Here is an image of my debugger showing the error in your code:
I know a fix was promised a few days ago, but this looks like an old bug.
Time until fix?
Kind Regards, Garry.
