Upload dSYMS to Firebase via Fastlane

I am struggling to upload dSYM files to Firebase via Fastlane. I have a lane that looks like the following:

desc "Fetch and upload dSYM files to Firebase Crashlytics"
lane :refresh_dsyms_firebase do |options|
  download_dsyms(version: options[:version])        
  upload_symbols_to_crashlytics(gsp_path: "./App/GoogleService-Info.plist") 
  clean_build_artifacts
end

I confirmed that that is the correct path to the plist file, but when I try to run the lane at first I see the following:

[17:22:47]: invalid byte sequence in UTF-8
[17:22:47]: invalid byte sequence in UTF-8
[17:22:47]: invalid byte sequence in UTF-8

and then one of these for every dSYM file found:

[17:22:48]: Uploading '70DBE65E-227E-3754-89F2-EEFA6B8EEC2F.dSYM'...
[17:22:48]: Shell command exited with exit status  instead of 0.

I am trying to determine exactly what I am missing from this process. Does anyone have ideas? I am fairly new to Fastlane, so definitely assume I could be missing something basic. (Although, that empty exit status is a bit weird).

fastlane 2.107.0

EDIT(June 7th: 2021): I updated the answer from my own to one that was helpful to me at the time this was written.

There are many other great answers on this page on using Fastlane as well - please check them out

Solution

  • This may not be an option for most, but I just ended up fixing this by starting over. It may not be entirely obvious if you came over from Fabric, but I figured I would just rip off the band aid. My original setup was using the Fabric(Answers)/Firebase Crashlytics which is the Fabric->Firebase migration path, although subtle, the configuration between the two are slightly different and cause issues with upload_symbols_to_crashlytics

    1. Remove support for Fabric answers, or replace with https://firebase.google.com/docs/analytics/ios/start
    2. Remove the Fabric declaration in Info.plist
    3. Modify your existing run script in BuildPhases: replace your existing runscript with "${PODS_ROOT}/Fabric/run" and add $(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH) to input files
    4. In you AppDelegate remove Fabric.with([Crashlytics.self]) and you can also kill the import Fabric as this is now covered by Firebase
    5. Unlink fabric, re-onboard Firebase crashlytics, and select new integration. 
    desc "Upload any dsyms in the current directory to crashlytics"
lane :upload_dsyms do |options|
  download_dsyms(version: version_number, build_number: build_number)
  upload_symbols_to_crashlytics(gsp_path: "./App/Resources/GoogleService-Info.plist")
  clean_build_artifacts
end
