Firebase crashes unreadable - ios

Question

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

Answer 1

Your upload script doesn't appear to be setting the GOOGLE_APP_ID var.It should something like:
# Replace this with the GOOGLE_APP_ID from your GoogleService-Info.plist file
1:xxxxxxxxx:ios:xxxxxxxxxxx=1:my:app:id
# Replace the /Path/To/ServiceAccount.json with the path to the key you just downloaded
"${PODS_ROOT}"/FirebaseCrash/upload-sym "firebasecrash/firebasecrashreport.json"
Here firebasecrashreport.json is name of ServiceAccount JSON file and firebasecrash is name of my project.

Answer 2

Your upload script doesn't appear to be setting the GOOGLE_APP_ID env var. The upload run script step should look something like the following:
# Replace this with the GOOGLE_APP_ID from your GoogleService-Info.plist file
GOOGLE_APP_ID=1:1234567890123:ios:1234abc567de89
# Replace the /Path/To/ServiceAccount.json with the path to the key you just downloaded
"${PODS_ROOT}"/FirebaseCrash/upload-sym "/Users/yourname/yourproject/Your Project Name-5632e387efda6.json"
The below question I answered is a problem similar to yours.
Firebase iOS multiple errors when uploading symbol files

Answer 3

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:
