isTeamMember returns string instead of boolean

[glebviniarskii]

echo "output 1 ${{steps.teamAffiliation.outputs.isTeamMember == 'false'}}"
echo "output 2 ${{steps.teamAffiliation.outputs.isTeamMember == 'true'}}"
echo "output 3 ${{steps.teamAffiliation.outputs.isTeamMember == false}}"
echo "output 4 ${{!steps.teamAffiliation.outputs.isTeamMember}}"

Really curious about this behavior, first noticed it when if returned false from false == false expression in checking conditions for step

That is correct, outputs are always strings.

The behavior for comparisons in expressions is documented here (see the Note)

If you want to force coercion to a boolean you can do something like this

echo "output 2 ${{ fromJSON(steps.teamAffiliation.outputs.isTeamMember) == true}}"

Some examples

echo ${{ false == 'false' }} # false
echo ${{ 'false' == false }} # false
echo ${{ fromJSON('false') == false }} # true

So it is always better to compare strings for equality

Apologies for the vagueness in the README that lead to this confusion I will add a note to make it more clear.

@glebviniarskii created issue #25 to make this clear.

Thank you for bringing this up
