Operation element is not declared

We were doing load testing of one of the interfaces which sends message to destination using WCF-WebHttp adapter configured dynamically in orches07ation. Not much load - just 100 messages in few minutes, but found that 5 of the messages got suspended.

This was bit confusing as until now all went fine in all the env and no suspended messages, except here in Performance env.

Operation element is not declared


Why it happened

After looking out for this error, found that this is known issue with WCF-WebHTTP adapter along with Dynamic send Port when under load.

What to do

You need to apply the cumulative update provided by Microsoft, which can be found at following link:

The request has both SAS authentication scheme and 'Bearer' authorization scheme. Only one scheme should be used

Image
While doing testing after doing a POC on Securing Logic App with Azure Active Directory authentication , where I have put logic app behind APIM and before passing the request to logic app, apim does validation of the token.  I was encountered with an error "The request has both SAS authentication scheme and 'Bearer' authorization  scheme.  Only one scheme should be used." Why it happened After validating the token which is part of the header i.e. Authorization, APIM forwards the request as it is to backend. As  Logic app is configured as  back end , it's url already consist of SAS signature plus the request also has Authorization section and this is the problem. By default every request endpoint on a logic app has a Shared Access Signature (SAS) in the endpoint's URL, which follows this format: https://<request-endpoint-URI>sp=<permissions>sv...

Getting Started with Logic Apps - AS2

Image
What is AS2? Every enterprise requires some kind of product, service or counselling from another enterprises thus there happens a B2B(business to business) communications, some of the communication is unique whereas most of the communications are common for most of the enterprises e.g., Purchase Order. But every enterprise has there own way(format) of sending the messages, leading to difficult management when number of partners increased.  Considering this the Enterprise leaders decided to have some standards/rules defined across the communication leading to B2B protocol standards which provide guidelines for trading partners to follow when conducting business between enterprises. EDI X12, EDIFACT, TRADACOM etc. AS2 stands for Applicability Statement 2 and is a B2B messaging protocol used to transmit Electronic Data Interchange (EDI)/Business documents from one organization to another. So EDI standards define how to format data and AS2 specifies how to securely transport...

How to Debug and Trace request in Azure APIM - Portal, Postman, RequestBin

Image
Introduction  APIM is a great option to expose API's with out of box features for applying restrictions, preprocessing, postprocessing etc. You can leverage existing API's,  by importing it and it gets added as a new API with all the operations associated with it. And based on the requirements you  apply policies at the stage/level (Inbound,Backend/Outbound) and you are ready to use the API. Before it is shared, we do some testing to make sure everything is working as per the expectation and this is where Debugging and Tracing request becomes important. APIM does provide a way to Trace a call with the help of  Ocp-Apim-Trace http header. So whichever request/call is to be traced, it needs to include this in header  with the value set to true and it has dependency on another header, so that also needs to be passed i.e.  Ocp-Apim-Subscription-Key Note: The api on which Tracing is to applied , it requires the subscription key to be en...
