IAP with LB and cloud run cross origin resource policy error

[andreybu]

Hello community, 

I have a problem with IAP with Application Load Balancer and cloud run as backend. 

Getting this error 

Already tried to add custom headers to LB, but no luck

Also tried to add next policy to IAP, also not working for me

gcloud iap settings set iap.yaml --project=competitions-staging --resource-type=compute

gcloud iap settings set iap.yaml --project=competitions-staging --resource-type=iap_web

cat iap.yaml
access_settings:
cors_settings:
allow_http_options: "true"

Could someone please help with this issue

I also found and enabled this setting in IAP Backend Services but it doesn't help

After page refresh error disappear but after clearing cookies I see it again

[andreybu]

Any suggestions? I'm really stuck with it, will be very appreciate for advises and help
