Description

When I enable promptCaching for Claude Sonnet 4, all inference requests fail and I receive the following error in the Continue logs:
"crypto is not defined."
I also tried uninstalling the Continue plugin and deleting the ~/.continue directory. After reinstalling and adding my config.yaml file, the same problem occurred. Please investigate and fix this error.

NOTE: Commenting out promptCaching: true in the config.yaml file and restarting PHPStorm is a work around that fixes the issue.

To reproduce

1. Add Claude Sonnet 4 model in the config.yaml file.
2. Be sure to add promptCaching: true to the model
3. Save the config.yaml file
4. Run an inference request
5. Error message is displayed by the Continue plugin: "crypto is not defined"

I tried the following config and did not get any error:

models:
  - uses: anthropic/claude-4-sonnet
    with:
      ANTHROPIC_API_KEY: <key>
    override:
      defaultCompletionOptions:
        promptCaching: true

@Patrick-Erichsen I wonder if it's a bedrock specific issue?
