Heyyyy 👋 I have a fix for this ^ This should be released in the next version 😊

Over in https://github.com/fastlane/fastlane/issues/12789, which is the actual problem which is causing problems for you in a totally different place, I posted some instructions on how to use a special variant of the current fastlane version that gives some output that might help us understand what is going on: https://github.com/fastlane/fastlane/issues/12789#issuecomment-444942320 Would be nice if some of you could jump over there and report back. I will try to iterate then and somehow figure out what is going on.

@janpio @domzilla Yeah happens every time for me as well. Local machine as well.

And for me also without --skip_screenshots.

p.s. one weird thing I noticed is that fastlane env spits out version 2.105.2, although the installation source points to the latest fastlane version 🤔.

| Installation Source         | ~/foo/bar/vendor/bundle/ruby/2.5.0/gems/fastlane-2.108.0/bin/fastlane |
...
fastlane | 2.105.2 | 🚫 Update available

Note that I’m using a script that installs the latest fastlane, but that shouldn’t matter as @domzilla points out that the issue also persists for them.

GEMSET_PATH=vendor/bundle
bundle install --path ${GEMSET_PATH}
# forward all arguments to deliver
bundle exec fastlane deliver "$@"

But since I’m not the only one having the problem I guess it’s not related to the version mismatch.

@janpio The issue is consistent on every fastlane deliver across different apps. I’m using it on my local machine. It also happens without –skip_screenshots.

domzilla on Nov 19, 2018

I have the same error.

@angelsubirana @adi101010 Meanwhile if you do not rely too much on the HTML Preview file you can run the command with --force switch like that: fastlane deliver run --force = true
