Logic App API Connection Error : Storage account access key should be a correct base64 encoded string

Question

I created a logic app with a storage api connection. However, I get this error : Storage account access key should be a correct base64 encoded string. I created the logic app through arm template.

If I edit the api connection, provide the same value again, initially it gives the same error, but after some time this error goes.

It would be helpful to know why this issue is coming up and how to overcome it.

Thanks.

Hi @Kothai Ramanathan

Due to character limit posting as answer. Are you defining the "Microsoft.Web/connections" in your ARM templated or just referring the existing connection. As it looks like the value are not correctly specified in the Microsoft.Web/connections therefore when you reconfigure it works fine. For your reference sharing from the below from quick start templates.

 "resources": [  
        {  
            "type": "Microsoft.Web/connections",  
            "apiVersion": "2018-07-01-preview",  
            "name": "[parameters('storageConnectionName')]",  
            "location": "[parameters('location')]",  
            "dependsOn": [  
                "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountName'))]"  
            ],  
            "properties": {  
                "api": {  
                    "id": "[subscriptionResourceId('Microsoft.Web/locations/managedApis', parameters('location'), 'azureblob')]"  
                },  
                "parameterValues": {  
                    "accountName": "[parameters('storageAccountName')]",  
                    "accessKey": "[listKeys(variables('storageAccountId'), '2019-04-01').keys[0].value]"  
                },  
                "testLinks": [  
                    {  
                        "requestUri": "[uri(parameters('azureMgmtUri'), concat('subscriptions/', subscription().subscriptionId, '/resourceGroups/', resourceGroup().name, '/providers/Microsoft.Web/connections/', parameters('storageConnectionName'), '/extensions/proxy/testconnection?api-version=2018-07-01-preview'))]",  
                        "method": "get"  
                    }  
                ]  
            }  
        }
