You deployed a Cloud Function but it fails with error: "Function failed to deploy: Invalid runtime specified." What is the most likely cause?
AThe trigger type is missing
BThe function code has syntax errors
CThe runtime value is misspelled or unsupported
DThe function name is too long
Step-by-Step Solution
Solution:

  1. Step 1: Interpret error message

    The error states invalid runtime, meaning the runtime specified is not recognized or misspelled.

  2. Step 2: Check other options

    Syntax errors or missing trigger cause different errors. Function name length rarely causes this error.

  3. Final Answer:

    The runtime value is misspelled or unsupported -> Option C

  4. Quick Check:

    Invalid runtime error = wrong runtime name [OK]
Quick Trick: Check runtime spelling and support when deployment fails [OK]
Common Mistakes:
  • Blaming code syntax
  • Ignoring runtime spelling
  • Assuming trigger missing causes this error
