Conflict between Fastlane and Firebase App Distribution

[only2433]

I have been using Fastlane to automate the distribution of my Android (AOS) app. After updating to Firebase App Distribution 0.9.1, an error occurs, and the distribution fails.

My Fastlane version is 2.220.0.

The error message is:

[11:21:08]: 59: end
[11:21:08]: 60: end
[11:21:08]: => 61: xczvxzcvl;kjb `````` ``

[!] Syntax error in your Fastfile on line 61: Fastfile:61: syntax error, unexpected backtick literal, expecting end-of-input
