How are you creating the SAS token? Please edit your question and include that. – Gaurav Mantri

In the Storage Account > SAS Menu > Selecting Table and permissions as list and then generating the SAS URL/tokens.

Answer 1

The error occurs if you are not passing valid SAS token while calling the API. Initially, I too got same error when I ran the API with extra space after sig like this:

GET https://storageaccname.table.core.windows.net/Tables?SASToken

Response:

To resolve the error, generate the SAS token with correct permissions and include it properly with valid signature while calling API.

In my case, I generated SAS token by selecting below permissions:

When I called the REST API again with valid SAS token by removing extra space at the end, I got the response successfully with list of tables like this:

GET https://storageaccname.table.core.windows.net/Tables?SASToken
