Problems creating sharp Lambda layer package with custom libvips about sharp

[lovell]

Did you see https://github.com/zoellner/sharp-heic-lambda-layer ?

Thanks for the prompt answer. It was just updated using the latest versions...I'll try it out; even though the compile steps are very similar to mine. Will update this ticket when I confirm it works.

Unfortunately, the Lambda layer from the other project seems not to work. The error I am getting is below.

{
  "errorType": "Error",
  "errorMessage": "Input buffer contains unsupported image format",
  "trace": [
    "Error: Input buffer contains unsupported image format",
    "    at Sharp.metadata (/opt/nodejs/node_modules/sharp/lib/input.js:486:17)",
    "    at getFileMetadata (/var/task/index.js:1351:40)",
    "    at Runtime.handler (/var/task/index.js:1377:26)",
    "    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"
  ]
}

I created a ticket there (zoellner/sharp-heic-lambda-layer#30); maybe the issue with building both Lambda layers is related.

Is there any documentation on which exact files are needed at runtime after the compilation from source is done?

[lovell]

@zoellner You can use ldd to list the shared libraries required by a compiled binary, e.g.:

$ ldd node_modules/sharp/src/build/Release/sharp-linux-x64.node

@lovell got it fixed. The issue for me was related to a wrong preset during the libheif compilation. Code is available here: https://github.com/Dobe-Solutions/sharp-heif-lambda-layer
