Azure Blob SAS Token generated using APIM failing intermittent at Blob

[saichaithanyathota]

Hi Team,

Good day!!

We have tried to refere the generate shared access token policy snippet code for generating SAS Token using Azure APIM.

During testing we found that SAS Tokens generated are failing to authenticate at storage account and further deep dive we figured out that the SAS Token signatures consisting of the specail charchter '+' is failing to authenticate.

sample Signature for failed case: sig=VBc5wxRxaYtPOVVPtzTq7I5Fsc2uvNU2whpEq790+l2

We have raised an MS Support ticket for the same and they have asked us to raise a issue in the git hub.

Can you please let us know in which cases does this specail symbol + occurs and how to avoid it while generating SAS Code?

Please let us know incsae of any additional queries

Best Regards:
Sai
