sam/cfn Code Suggestion does not appear

[subhash36]

Type: Performance Issue

I just installed the AWS ToolKit. Everything works fine except for the main feature which is the code suggestion.

Extension version: 1.85.0 VS Code version: Code 1.81.1 (6c3e3dba23e8fadc360aed75ce363ba185c49794, 2023-08-09T22:22:42.175Z) OS version: Windows_NT x64 10.0.19045 Modes:

I had tried disabling and reinstalling the extension. Re-installed VS Code itself but to no luck.

Assuming you referring to CodeWhisperer, you need to login before CodeWhisperer will work.

Can you provide the exact steps you took and what you tried, what kind of code file are you editing?

[subhash36]

I'm referring to the auto suggestion feature while writing CFT files. It is one of the features where the key words of the CFT yaml/json syntax is auto suggested. I did try the CodeWhisperer, logged in and everything, but I guess it doesn't suggest code for yaml/json files.

Thanks, I see this is a duplicate of https://github.com/aws/aws-toolkit-vscode/issues/3752

CodeWhisperer doesn't provide completion for SAM/CloudFormation JSON or YAML template files, but AWS Toolkit does automatically fetch SAM/CFN JSON schema and configures vscode so that autocompletion and syntax validation should work.
