Hi @Iditb,
it seems you need to specify a fastlane deliver command’s flag: --itc_provider .
This flag is not wired in as a step input for the Deploy to iTunes Connect step,
but the step has an input: Additional options for deliver call, this input allows you to specify additional flag for the deliver call.
To get your itc provider pls run:
pathToXcode.app/Contents/Applications/Application\ Loader.app/Contents/itms/bin/iTMSTransporter \
-m provider \
-u 'USERNAME' \
-p 'PASSWORD' \
-account_type itunes_connect \
-v off
once you get your provider specify the Additional options for deliver call: --itc_provider YOUR_PROVIDER input of the Deploy to iTunes Connect step.
