Unable to debug this issue for a week. I tried to check if there is a conflict with any of the plugins that are being used. But was not able to figure it out. How do I fix this?

Solution

Try to replace this plugin:

"@capacitor-firebase/authentication": "^0.3.1"

with the current version of it:

"@capacitor-firebase/authentication": "^0.5.0"

Also see this issue comment, which may or may not be still actual.
