Hello,
Can you please review this PR. The error in the CircleCI is unrelated to my code.

@redaguermas rerean tests and passed but looks like you uploaded several of your ide files with this pr and your package-lock file. Can you please remove all those files and maybe add a test case for the new state added

[robertrmartinez]

@redaguermas Yeah please remove all of your extra files.

Should just be only two files, the bid adapter, and the associated _spec file testing the change.

package-lock should not be in there either.

[bretg]

please also remove nobidBidAdapter.js.orig and the changes to package-lock.json
