(2025.12 - 2025.12.01) Non-admin users unable to share VDIs

[Mohjeet]

Bug description

Non-admin users cannot share VDIs due to an empty permission profile dropdown. This occurs due to a API authorization failure, preventing the dropdown from being populated.

Affected versions

2025.12 and 2025.12.01

Mitigation

1. Download patch_lambda.py and updated function code zip for version 2025.12 and 2025.12.01 by replacing <output-directory> with the directory to download the patch file and patch script in the command below:
   1. The patch file requires AWS CLI v2, Python 3.9.16 or above, and Boto3.
   2. Configure the AWS CLI for the account / region where RES is deployed, and make sure that you have Lambda permissions to update function code.

   3. OUTPUT_DIRECTORY=<output-directory>
       
      mkdir -p ${OUTPUT_DIRECTORY}
      curl https://research-engineering-studio-us-east-1.s3.us-east-1.amazonaws.com/releases/2025.12/patch_scripts/patch_lambda.py --output ${OUTPUT_DIRECTORY}/patch_lambda.py
      curl https://research-engineering-studio-us-east-1.s3.us-east-1.amazonaws.com/releases/2025.12/patch_scripts/patches/virtual_desktop_utils_controller-17000e96.zip --output ${OUTPUT_DIRECTORY}/virtual_desktop_utils_controller-17000e96.zip
      

2. Update the lambda function code by running the following patch command by replacing <environment-name> with the RES environment name:

   1. ENVIRONMENT_NAME=<environment-name>
      
      python3 ${OUTPUT_DIRECTORY}/patch_lambda.py --zip-file ${OUTPUT_DIRECTORY}/virtual_desktop_utils_controller-17000e96.zip --lambda-name ${ENVIRONMENT_NAME}-backend-lambda
      

Once the patch has been applied the Last modified attribute of the Lambda function should be recent, and non-admin users will be able to successfully retrieve the list of permission profiles and be able to share VDIs.
