[timoshenkoav]

try to set the escaped string as value - not direct json

[wecrtech]

@timoshenkoav Sorry, an error again with escaped string

[timoshenkoav]

oh, sorry. wrap(escape) only credentials field, here is the example

{
  "credentials":"{\"type\":\"service_account\",\"project_id\":\"xxx\",\"private_key_id\":\"xxx\",\"private_key\":\"...\\n\",\"client_email\":\"xxx@yyy.iam.gserviceaccount.com\",\"client_id\":\"zzz\",\"auth_uri\":\"https://accounts.google.com/o/oauth2/auth\",\"token_uri\":\"https://accounts.google.com/o/oauth2/token\",\"auth_provider_x509_cert_url\":\"https://www.googleapis.com/oauth2/v1/certs\",\"client_x509_cert_url\":\"https://www.googleapis.com/robot/v1/metadata/x509/yyy.iam.gserviceaccount.com\"}",

Please check the service account permissions to access payments/purchases

[wecrtech]

@timoshenkoav We can not find "access service account", we searched but we find nothing, can you please help us? . Thanks for your support

[wecrtech]

Hello @timoshenkoav, We made sure that the the service account has all permissions to access payments/purchases and still give me the same error!

[wecrtech]

We already missed purchase permission once we enable it it works fine now, Thanks
