Metadata file does not contain metadata

Question

I don't know what's going on here. I was able to create an APK for Android. So, it should be easy to make it a Facebook/WebGL game too, right? Apparently not.

 error CS0009: Metadata file `C:\...\Library/FacebookSDK/CanvasJSSDKBindings.jslib' does not contain valid metadata

I don't know what to do with this. I tried deleting it and letting it rebuild. I tried deleting everything in the project (except assets) and let all of that rebuild. I'm using Facebook SDK version 7.12.2. I'm using Unity 2017.3.1f1.

Deleting folder [game path]\Library\FacebookSDK works for me. You need to verify there is not a file named CanvasJSSDKBindings.jslib in this location.

You must have the following files inside the folder:

Facebook.Unity.dll
Facebook.Unity.Gameroom.dll
Facebook.Unity.Settings.dll
FacebookNamedPipeClient.dll
ivy.xml
version.txt

The contents of ivy.xml must be:

 `<?xml version="1.0" encoding="utf-8"?>
 <ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">
    <info organisation="Facebook" module="FacebookSDK" e:packageType="UnityExtension">
      <description>Facebook SDK</description>
    </info>
    <publications>
       <artifact name="Facebook.Unity" type="dll" ext="dll" e:guid="2403d1f95ea54028853403e595bc9274" />
       <artifact name="Facebook.Unity.Gameroom" type="dll" ext="dll" e:guid="063ad293d9fe40e18bde10bbc71df334" />
       <artifact name="Facebook.Unity.Settings" type="dll" ext="dll" e:guid="18b4dbf8a0b54ea4adf46fb7f4d71dd0" />
       <artifact name="FacebookNamedPipeClient" type="dll" ext="dll" e:guid="51288a4fc4384861a5b1f9dd49b3da26" />
    </publications>
 </ivy-module>`

I'm using Unity 2018.1.6f1 and Facebook SDK 7.13.0.
