Try to join meeting without password and get this error
MY CODE
I used 1.7.7 cdn version.
Also can’t join with password to another meeting.
Meetings is not fictional
What it can be?
Hey @ivetta,
Make sure to always include the passWord property when joining the meeting.
If there is no password, set it to an empty string: password:""
If there is a password, set it to the password: password:"asdfasdf"
Let me know if that helps.
Thanks,
Tommy
The reason was in “leaveUrl”. It must be use window.location.href, but window.location was used.
Happy you figured it out! Thanks for posting the solution!
