az rest deployment to flex function results in broken response #30960

michaelwestcotthelfie · 2025-03-06T03:29:42Z

Describe the bug

I'm trying to update a flex-consumption azure function using the az rest api. The command I am using is below (I've removed any sensitive information). The deployment succeeds, but the response from the API includes some HTML AFTER the JSON.

This causes the command to fail as it tries to pass the response as JSON.

Related command

az rest --method PUT \
        --uri "https://management.azure.com/subscriptions/xxxxx/resourceGroups/xxxxx/providers/Microsoft.Web/sites/func-xxxxxx/extensions/onedeploy?api-version=2024-04-01" \
        --body "{
                \"properties\": {
                    \"packageUri\": \"${APP_URL}\"
                },
                \"type\": \"zip\"
        }"

            <b> Description: </b>An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
            <br><br>

            <b>Details:</b> To enable the details of this specific error message to be viewable on remote machines, please create a &lt;customErrors&gt; tag within a &quot;web.config&quot; configuration file located in the root directory of the current web application. This &lt;customErrors&gt; tag should then have its &quot;mode&quot; attribute set to &quot;Off&quot;.<br><br>
