Application fails to start when ENV variable is missing

[kajihiroshi]

Description

The application crashes on startup if the API_BASE_URL environment
variable is not defined.

Expected Behavior

The app should either use a default value or fail with a clear error
message.

Actual Behavior

The app throws a runtime error without a helpful message.

Thanks for reporting.

We should validate required environment variables at startup and
provide a clear error message when they are missing.
I'll add validation logic.

agree

thanks

[khiroshi-dev615]

Thanks for reporting this.

You're right — the app currently does not handle missing environment
variables properly. We'll add validation and a clearer error message.

[khiroshi-dev615]

Confirmed.

The application assumes API_BASE_URL is always defined, which causes
a crash when it's missing. We should fail fast with a descriptive error.

[kajihiroshi]

Good catch.

We'll add a startup check for required environment variables and
throw a readable error instead of failing at runtime.

[osamumori-dev]

This happens because the app accesses process.env.API_BASE_URL
directly without validation.

We'll introduce environment validation during initialization so
missing variables are detected early.

Thanks for the report.

We should validate required environment variables at startup and
either provide defaults or exit with a clear error message.
I'll address this in the next update.

[thomaspapp28]

Yep, this is on us.

We’re missing env validation at startup. I’ll add a check so the app
fails with a clear message instead of crashing.

[osamumori-dev]

Confirmed.

Failing silently on missing environment variables is risky,
especially in production. We'll add strict validation to prevent
this from happening.

[osamumori-dev]

Good report.

We'll introduce environment variable validation (possibly using a
schema-based approach) to ensure required values are present before
the app starts.

[m-osamu615]

Thank you for the detailed report.

The current behavior is not ideal. Required environment variables
should be validated at startup, and the application should fail with
a clear, actionable error message when they are missing.
We'll update this accordingly.

Good catch. The app currently assumes this env variable exists, so we’ll add validation to prevent an unclear runtime crash.
