Ran into this error  "Source position should be specified and must be greater than 0 for applications with multiple sources" and trying to make my app sync policy from manual to auto argocd app set cert-manager-dev --sync-policy automated So in our setup we have multiple (2 sources) and it gets confused which one to used for our app sync process.   

We meed to install argocd :- kubectl create namespace argocd kubectl apply -n argocd --server-side --force-conflicts -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml Make sure we have argocd app server up and running kubectl port-forward svc/argocd-server -n argocd 8080 :443 To create a temporarily initial password to login argocd admin initial-password -n argocd To login to argocd run the following commands:-  argocd login localhost:8080 Lets create an app  argocd app create guestbook --repo https://github.com/argoproj/argocd-example-apps.git --path guestbook --dest-server https://kubernetes.default.svc --dest-namespace default Then sync the code changes :-  argocd app sync guestbook To list the app argocd app list  Get the app in details argocd app get guestbook To disable sync  argocd app set  guestbook --sync-policy manual To terminate sync   argocd app terminate-op cert-manager...

To resolve this, we need to setup function app stack settings version to python 3.13 as shown below :- And then deploy your function app. Please remember to ensure you don't have any current deployment that's using 3.14.   

Bump into the error while trying to run apollo router.   Anonymous usage data is gathered to inform Apollo product development. See https://go.apollo.dev/o/privacy for details. 2026-07-16T09:46:43.188554Z ERROR failed to read supergraph schema reason=stream did not contain valid UTF-8 2026-07-16T09:46:43.234786Z INFO state machine transitioned event="NoMoreSchema" state=Errored previous_state="Startup" 2026-07-16T09:46:43.235259Z INFO stopped 2026-07-16T09:46:43.235740Z ERROR no valid schema was supplied no valid schema was supplied To resolve this error   rover supergraph compose --config ./supergraph.yaml | Out-File -Encoding utf8 supergraph.graphql and then re--run router  c:\tools\router --config router.yaml --supergraph supergraph.graphql  

  To compose your supergraph, first we need to create individual schema for example product, review and user graphql schema. And we also need a supergraph.yaml first subgraphs :   product :     routing_url : http://localhost:4001/graphql     schema :       file : ./product.graphql   # ← points AT the schema you already wrote   user :     routing_url : http://localhost:4002/graphql     schema :       file : ./user.graphql   review :     routing_url : http://localhost:4003/graphql     schema :       file : ./review.graphql Let's create our supergraph rover supergraph compose --config ./supergraph.yaml > supergraph.graphql If you're using powershell rover supergraph compose --config ./supergraph.yaml | Out-File -Encoding utf8 supergraph.graphql We will now have a combined supergraph schema that includes product, review and user graphql.

 The following code allows us to setup a server and then expose a tool called hello_mcp. Ensure you start azurite and then run "func host start" to run the server import azure . functions as func import logging app = func . FunctionApp ( http_auth_level = func . AuthLevel . ANONYMOUS ) @ app . mcp_tool_trigger (     arg_name = " context " ,     type = " mcpToolTrigger " ,     tool_name = " hello_mcp " ,     description = " Hello world. " ,     toolProperties = " [] " , ) def mcp_trigger ( context ) -> None :     return " Hello I am MCPTool! " And during runtime, we will see the following endpoint  Then we can also call it using the following client side code where we are caling it using streamable http. """ Simple MCP client that connects to a local Azure Functions MCP endpoint (the mcpToolTrigger extension approach) and calls the `hello_mcp` tool. Install dependency first:     pip install ...

We can create self hosted python mcp server code using the following command line:- azd init --template mcp-sdk-functions-hosting-python -e mcpsdkserver-python This will create a bunch of code that allow you to run your mcp server using FastMCP package.  You can see more of the code here  https://github.com/kepungnzai/az-function-mcp-self-hosted

We can easily create a logic app that run "When http request is triggered" and then send out email.  The logic app looks something like this :-  We will use the following json to define out schema  {"receipient": "test@example.com","title": "Hello","message": "This is a test"} And this us what our request body JSON schema would look like Then we will create "Send an email (v2)". In our send email parameter setup, it looks something like this. When our http triggers completes, it returns a json but it is also a STRING. And we need to be able to convert it into a json otherwise you will get the following errors :- Unable to process template language expressions in action 'Send_an_email_(V2)' inputs at line '0' and column '0': 'The template language expression 'triggerBody()?['receipient']' cannot be evaluated because property 'receipient' cannot be selected....
