 fastlane snapshot --capture_output does not work and says its an invalid option so I cannot add the log

Environment

 Using fastlane version 2.184.1 and xcode Version 12.5 (12E262) w/ SnapshotHelperVersion [1.25]

 SnapshotHelper.swift  keeps failing while trying to create a build I've added the error below

�[31m❌  �[0m/Users/christine/automator/builds/20210601172734/ios/4ece7424-99b1-46df-bf11-02ab2c87c5bf/RxMobileUITests/SnapshotHelper.swift:184:21: �[31mcall can throw but is not marked with 'try'�[0m

It seems like you have not included the output of fastlane env
To make it easier for us help you resolve this issue, please update the issue to include the output of fastlane env 👍

[minuscorp]

This is fixed for the next release, I'll close the issue but feel free to comment if any other issue arises.

[tmaly1980]

@minuscorp When will the release be ready? And how can I utilize the fix in the meantime?

[minuscorp]

You can always target your Gemfile to the master branch of fastlane, we release about once a week though.

[christin3]

@minuscorp Is this fix in 2.185.1? I couldn't find an associated tag with issue number. If this fix is in this git tag, I am still getting the same error.

[minuscorp]

Your issue is with the snapshot helper project or with Swift fastlane?

[christin3]

@minuscorp SnapshotHelper.swift, Its still thowing the same error, as above, after updating to the latest version of fastlane

[minuscorp]

I'll check it out asap!

[christin3]

@minuscorp by adding a try in front of try UIImagePNGRepresentation(image)?.write(to: path, options: .atomic) on line 184 in the SnapshotHelper.swift, fixed the issue.

[minuscorp]

I have to check this out during the weekend, to make sure this is still backwards compatible🙏
