The Deploy to Bitrise.io step can be used for attaching any artifact to the build, most of our steps share additional / debug logs which can help with debugging issues, and are stored in the $BITRISE_DEPLOY_DIR which is the default dir deployed by Deploy to Bitrise.io.

It seems the error code
25300 is simply that the item does not exist in the keychain. A possible debug idea:
-25300 is errSecItemNotFound, which is a pretty standard keychain error. To debug this, my recommendation is that, when it occurs, you dump out the contents of your keychain to verify that things are in the state that you expect them to be in.
