Hi,
I tested the 1.3.2 version and it fixes the previous issue.
Now, I have this error but I have a Distribution profile defined in my app.
Error:
Selected distribution type: app-store, but forgot to provide a Distribution type certificate.
Don’t worry, it’s really simple to fix! 
Simply upload a Distribution type certificate (.p12) on the workflow editor’s CodeSign tab and we’ll be building in no time!
Stacktrace (for debugging):

/var/folders/6q/wgy6jtp12w5gzgm9lzcglpqw0000gn/T/bitrise326158526/step_src/step.rb:76:in `’
I think this step is not compatible with Xcode 11 certificates yet.
Do you know when it will be fixed? (there is also an issue with the Project Info step not being able to read the new marketing version format).
