Liked RIP AWS Go Lambda Runtime | Mark Wolfe's Blog by Mark Wolfe 
Post details
Amazon Web Services (AWS) is deprecating the go1.x runtime on Lambda, this is currently scheduled for December 31, 2023. Customers need to migrate their Go based lambda functions to the al2.provided runtime, which uses Amazon Linux 2 as the execution environment. I think this is a bad thing for a couple of reasons: There is no automated migration path from existing Go Lambda functions to the new custom runtime. Customers will need to manually refactor and migrate each function to this new runtime, which this is time-consuming and error-prone.


Had anyone ever seen an error like this with #AWSLambda?

It's a Node 18 app that calls out to Renovate but fails due to some deep intenals in Node when doing some performance checking?

    "errorType": "TypeError",
    "errorMessage": "performance.markResourceTiming is not a function",
    "stack": [
        "TypeError: performance.markResourceTiming is not a function",
        "    at markResourceTiming (node:internal/deps/undici/undici:10636:21)",
        "    at finalizeAndReportTiming (node:internal/deps/undici/undici:10632:7)",
        "    at Object.handleFetchDone [as processResponseEndOfBody] (node:internal/deps/undici/undici:10579:45)",
        "    at node:internal/deps/undici/undici:10895:44",
        "    at node:internal/process/task_queues:140:7",
        "    at AsyncResource.runInAsyncScope (node:async_hooks:204:9)",
        "    at AsyncResource.runMicrotask (node:internal/process/task_queues:137:8)",
        "    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"

Very odd, and this Go issue is the only thing I could find that may relate πŸ€”
