Are there any changes in AWS Signature recently. I tried the above S3 upload using webservice but getting below error.

Any latest reference is helpful.

<Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message>

- Generate a xsd from the xml

- upload in XML Schema 

- Create a DTL and select XML

- Map it with your HL7

I have added the remote intersystems servers with nameservers in VS Code. 

I can view/edit/Import and compile the class files in VS Code from my local system through workspace as shown in below screenshot.

I need this workspace to be mapped to TFS source control to track the code changes and also to Check IN/OUT to repository.

Thanks for your replied. I have tried with 

1. TFS extension for Visual Studio Code
2. TFVC for VS Code
Configured the vscode-tfvc.tfExePath also, but i could not check in/check out intersystems code.
Not sure how to make the classes writable in TF.exe's configured workspace.
