Failing step
- [7/8] RUN npm run compile

Exact error messages (preserve exact text)
- Error HH1201: Cannot find a value for the configuration variable 'MNEMONIC'. Use 'npx hardhat vars set MNEMONIC' to set it or 'npx hardhat vars setup' to list all the configuration variables used by this project.
- HardhatError: HH1201: Cannot find a value for the configuration variable 'MNEMONIC'. Use 'npx hardhat vars set MNEMONIC' to set it or 'npx hardhat vars setup' to list all the configuration variables used by this project.

Additional context from the log
- The error originates in hardhat.config.ts (MNEMONIC referenced at hardhat.config.ts:12:31).
- Exit code: The failing command exited with code 1 (as shown by the overall failure: "process \"/bin/sh -c npm run compile\" did not complete successfully: exit code: 1" and the Dockerfile step indicator).

Missing packages/files / configuration issues
- Missing configuration value: MNEMONIC. Hardhat cannot proceed because MNEMONIC is not set in the environment/Hardhat var store.
- Guidance: set MNEMONIC via:
  - npx hardhat vars set MNEMONIC
  - or npx hardhat vars setup to list all required config variables

Version information
- The build run shows standard npm install output; a note indicates a newer npm version is available: "New minor version of npm available! 11.9.0 -> 11.11.1" (not causative of the failure). No explicit version mismatch caused the error.

ERROR SUMMARY

- Exact error message and exit code:
  - Error HH1201: Cannot find a value for the configuration variable 'MNEMONIC'. Use 'npx hardhat vars set MNEMONIC' to set it or 'npx hardhat vars setup' to list all the configuration variables used by this project.
  - HardhatError: HH1201: Cannot find a value for the configuration variable 'MNEMONIC'. Use 'npx hardhat vars set MNEMONIC' to set it or 'npx hardhat vars setup' to list all the configuration variables used by this project.
  - Exit code: 1

- Failing command/step:
  - RUN npx hardhat compile (step [7/8]); Dockerfile line 23

- Missing packages or files mentioned:
  - MNEMONIC configuration value is not provided (Hardhat config requires MNEMONIC).
  - Warning about secret handling: SecretsUsedInArgOrEnv: Do not use ARG or ENV instructions for sensitive data (ENV "INFURA_API_KEY") (line 7)

- Version/mismatch information:
  - npm install completed with multiple deprecation warnings (e.g., glob, eslint).
  - Notice: New minor version of npm available! 11.9.0 -> 11.11.1
  - No explicit library version mismatch shown; failure stems from missing MNEMONIC rather than dependency version conflicts.

- Context:
  - The error occurs during Hardhat configuration parsing (hardhat.config.ts:12:31) while running hardhat compile in the Docker build.

Summary (under 1500 chars)

- Failing step/command:
  [ 7/10] RUN printf 'test test test test test test test test test test test junk\n' | npx hardhat vars set MNEMONIC

- Exact error message and exit code:
  Error: readline was closed
  ...
  Docker exit code: 1
  (The log ends with: "ERROR: process "/bin/sh -c printf 'test test test test test test test test test test test junk\\n' | npx hardhat vars set MNEMONIC" did not complete successfully: exit code: 1)

- Key failing detail:
  The failure occurs during a non-interactive attempt to set MNEMONIC via Hardhat:
  printf ... | npx hardhat vars set MNEMONIC
  The process fails because the readline prompt is closed during password/secret input handling:
  "readline was closed" with a stack trace indicating PasswordPrompt and enquirer prompt handling.

- Missing packages or files mentioned:
  None explicitly listed as missing. The error stems from an interactive prompt in a non-interactive Docker build, not a missing package/file.

- Version mismatch / warnings (not a hard mismatch, but relevant context):
  - npm warnings about deprecated packages (inflight@1.0.6, glob@8.1.0, @humanwhocodes/... object-schema, config-array, lodash.isequal, rimraf, eslint, etc.)
  - npm notice: New minor version of npm available: 11.9.0 -> 11.11.1
  - eslint@8.57.1 is no longer supported
  No explicit Node.js version mismatch; image is based on node:lts.

- Root cause: The Hardhat configuration variable MNEMONIC is not set. Hardhat is reading MNEMONIC from hardhat.config.ts:12:31 but no value is provided.

- Suggested fix:
  - Provide MNEMONIC (and any other required vars) via:
    - npx hardhat vars set MNEMONIC
    - or npx hardhat vars setup to list all required variables and provide values

- Version/ancillary:
  - npm notice: New minor version of npm available! 11.9.0 -> 11.11.1
  - To update: npm install -g npm@11.11.1

- Additional note: A warning about secrets usage was present (ENV "INFURA_API_KEY"); confidential data in ENV, but the build failure stems from the missing MNEMONIC value.
