412 Response Crashing App/Process

[ADNolan]

I am running into a case that when I receive an error, the AxiosError that is thrown crashes the app/process even when there are try/catch blocks at multiple levels. Tracking the issue to something in the SDK and it seems to originate from the getData method of the BaseQuery.

Versions Tested:

• Node Version v22.11.0
• "@contentstack/delivery-sdk": "4.5.0"
  • "@contentstack/core": "1.2.0"
• "@contentstack/delivery-sdk": "4.9.0"
  • "@contentstack/core": "1.3.0"

Snippet

try {
    this.log?.debug(`Querying ContentStack: ${JSON.stringify(query)}`);
    const rawData = await query.find<T>();
    const csData = this.doSomeTransforms<FindResponse<T>>(rawData});
    // ....Other processing

    return csData;
  } catch (e) {
    this.log?.error(e, 'Failed to query ContentStack');
    return null;
  }

Stacktrace:

/Users/me/path/to/project/node_modules/axios/dist/node/axios.cjs:2090
    reject(new AxiosError(
           ^

    data: `{"error_message":"We can't find that Stack. Please try again.","error_code":109,"errors":{"api_key":["is not valid."]}}`
    },
    status: 412

I can add the following and the unhandledReject does not crash the application.

process.on('unhandledRejection', err => {
  this.log.error(err.stack);
});

I am a bit lost on how/why the Axios Request that the SDK is making is not being handled by any of the try/catch blocks.

I have tracked down a bit more on this and its around using cache. This configuration causes a problem. I can update to ignore cache and error handling is back to "normal" so to say.

cacheOptions: {
    policy: Policy.NETWORK_ELSE_CACHE,
    storeType: 'memoryStorage',
    maxAge: 60000
}
