AWS Lambda Function Errors

[davidjwriter]

I'm using rusty-tesseract with a rust lambda function and I'm getting some strange results.

When I run everything locally it works great, super easy to use!

But as soon as I deploy to an AWS Lambda, it breaks with this error:

thread 'main' panicked at 'called Result::unwrap()on anErr value: CommandExitStatusError("exit status: 1", "Error in pixCreateNoInit: pixdata_malloc fail for data\nError in pixCreateTemplateNoInit: pixd not made\nError in pixCreateTemplate: pixd not made\nError in pixCopy: pixd not made\nError in pixGetDepth: pix not defined\nError in pixGetWpl: pix not defined\nError in pixGetYRes: pix not defined\nError in pixClone: pixs not defined\nPlease call SetImage before attempting recognition.\nError during processing.\n")', src/main.rs:158:74

I am deploying using Lambda Layers with pre-built Tesseract binaries. I have tried this with Tesseract v4 and v5 but get the same error each time. Here are the versions I've tried with:

The tesseract version is: "tesseract 4.1.3\n leptonica-1.82.0\n libjpeg 6b (libjpeg-turbo 2.0.90) : libpng 1.5.13 : libtiff 4.0.3 : zlib 1.2.7 : libwebp 0.3.0\n Found AVX2\n Found AVX\n Found FMA\n Found SSE\n"

And also v5:

The tesseract version is: "tesseract 5.3.2\n leptonica-1.83.1\n libjpeg 6b (libjpeg-turbo 2.0.90) : libpng 1.5.13 : libtiff 4.0.3 : zlib 1.2.7 : libwebp 0.3.0\n Found AVX2\n Found AVX\n Found FMA\n Found SSE4.1\n Found OpenMP 201511\n"

It is definitely a possible Lambda environment issue I haven't figured out yet, but I wanted to put this out there in case there is something else going on that you may want to know about.
