Product:

Microsoft Azure Blob storage

Problem:

Put a file on blob storage with POSTMAN.  https://www.postman.com/product/rest-client/

Get error  404 The specified blob does not exist

 

Solution:

Change to PUT instead of GET in postman program, to place a file on the blob storage.

As the file you are asking for does not exist – as you have not put it there yet – you get a 404 error.

To put a file on the blob storage you need to add headers like:

x-ms-blob-type  = BlockBlob

x-ms-date = 2022-11-02

 

Error like 400 Value for one of the query parameters specified in the request URI is invalid. can be that you miss the container name, only have the URL.

Error like 400 The requested URI does not represent any resource on the server. can be that you have not listed the file, only the container name in the URL.

Error like 403 This request is not authorized to perform this operation, can be that you are not logged into the VPN to give you access to the azure storage.

Error like 400 The requested URI does not represent any resource on the server. can be that the url does not contain the file to read in a get statement.

Error like 400 An HTTP header that’s mandatory for this request is not specified. can be that you are missing the x-ms-blob-type header.
