Firebase crashes unreadable

I have a problem reading crash reports on FireBase, my reports look like:

I've already followed these instructions to symbolicate the stacktrace, got the same result.

• I'm using Xcode 8
• My app is made in Swift 3
• Already wrote "FIRApp.configure()" in my appDelegate.didFinishLaunchingWithOptions method, did make it crash, deattach the debbuger, fix the error, re-run the app, got message "Crash successfully uploaded", etc...
• I'm using pods(pod 'Firebase' and pod 'Firebase/Crash')
• I see in the FireBase console my events and crashes(just are unreadable)
• Installed the script for symbolicate automatically on build(see image):

Already downloaded FireBase provided examples(crash example does not include the scripting for symbolicate automatically)

Already followed this solutions(which didn't work):

• link1
• link2

and many others.

Already visited last 6 months links on stackoverflow and google groups with this problem.

Nothing has worked, help please!!!

Update#1: I received an email from firebase-support@google.com saying:

reset your OAuth credentials

Didn't work, also I've been testing the script and the upload is correct, I'm starting to think is a Firebase bug

Finally, eureka!

I'm not sure about what was the mistake but I paste it here in case anyone is experiencig the same error:

1) I deleted my app on Firebase console

2) Create in Firebase console a new app with different name

3) Create and download a new GoogleService-Info.plist

4) Delete previous keys(rm $HOME/Library/Preferences/com.google.SymbolUpload*)

5) Create new firebase crash configuration

6) Copy the obtained file on step 5 to my root path on my project

7) Enable all permissions in firebase scripts

chmod -R 777 ./Pods/FirebaseCrash

8) Added the script phase as mentioned in the firebase configuration link mentioned in step 5 (I noticed that my not working previous configuration had blank spaces in name, so I created a non blank spaces name)

And finally(I don't know exactly wy) is working:
