Cannot use environment variable to set deploy.prerelease in .travis.yml

[Librazy]

I tried to automate my github prerelease/release deploy. I wish I could ship a release when my commit message start with some magic chars. So I wrote some bash script in before_deploy to set up a environment variable GHTHUB_DEPLOY_PRERELEASE, and set deploy.prerelease to

  prerelease: $GHTHUB_DEPLOY_PRERELEASE

everything works fine when preparing deploy.
But it says

For 'properties/prerelease', "false" is not a boolean. // See: https://developer.github.com/v3

when deploying application.

.travis.yml:
https://github.com/Librazy/TooltipFilter/blob/d767b946acd87a701e886c9d282032558e001917/.travis.yml

……Seems that environment variables are always strings?

Boolean values need to be handled in Releases options.

Any workaround now？
Can I call dpl directly then pass --prerelease=$GHTHUB_DEPLOY_PRERELEASE to it？

[BanzaiMan]

Arguments need to be processed by dpl into booleans, so that the GitHub API payload has correct data type (false vs "false").

I'm hitting the same issue. Is there a workaround?

One workaround would be to use deploy.on.condition to just skip the whole deploy. You need to duplicate all the other deploy config for each case, but since prerelease is a boolean there will only be 2.

I'm doing it here.

Following that issue. Same problem here.

Hello there. I've pushed a potential fix for this issue. Please test and report the results. Thank you.

provider: releases
edge:
  branch: releases-booleanize
⋮ # rest

(If you have multiple deployment providers, please adjust the definition accordingly.)

It works !
