While performing a list blob operation on my Azure Storage account, I got the response code 409 with FeatureVersionMismatch error.
The error message looks like below:
Invoking rest Azure List Blob API from Fiddler:
I spent some time to check what could be the cause until I saw the API version in the SAS token. We can see that it is using API version 2014-02-14. With this version, if you perform List blob operation on an azure storage container which contains an append blob it will result in the above error.
Use the updated API version after 2015-02-21.
If you are using the SDK, make sure you are using most recent Azure Storage SDK.
