How to fix "InvalidOperationException: This request has been blocked because sensitive information could be disclosed to a third party web sites when this is used in a GET request" ?

Root Cause #1:
Verbs not allowed

Resolution:

  • In the "web.config" file (C:\Program Files (x86)\UiPath\Orchestrator), set: verbs "AllowUnlisted = true"
  • This setting allows IIS to accept unlisted verbs. Take a look Configure Request Filtering In IIS .


Root Cause #2:
Event Viewer logs have the below errors -

Error-1:
[Quartz] Couldn't rollback ADO.NET connection. Transaction not connected, or was disconnected System.InvalidOperationException: Transaction not connected, or was disconnected
at void Quartz.Impl.AdoJobStore.ConnectionAndTransactionHolder.CheckNotZombied()

Error-2:
Error updating job state: System.Data.Entity.Core.EntityCommandExecutionException: An error occurred while reading from the store provider's data reader. See the inner exception for details. ---> System.Data.SqlClient.SqlException: The transaction log for database 'UiPath' is full due to 'AVAILABILITY_REPLICA'.

Resolution:
  • Perform database maintenance.
  • This is mostly possible in a HAA setup, but also check Event Viewer logs for normal setup as well.
