Downloaded url: https://socialify.git.ci/octomation/stub/png?description=1&font=Raleway&language=1&name=1&owner=1&pattern=Circuit%20Board&theme=Light

The error message

{
   "error":"Already initialized. The `initWasm()` function can be used only once.",
   "stack":"Error: Already initialized. The `initWasm()` function can be used only once.\n    at (vc/edge/function:74:6621)\n    at (vc/edge/function:74:6961)\n    at (vc/edge/function:74:7144)\n    at (vc/edge/function:81:14470)\n    at (vc/edge/function:14:16047)"
}

Also, I found that the emoji 🫥 isn't supported.

@wei, hi! Now I see

{"error":"unreachable","stack":"RuntimeError: unreachable\n    at (wasm://wasm/004f7a76:1:1194938)\n    at (wasm://wasm/004f7a76:1:1198329)\n    at (wasm://wasm/004f7a76:1:1198031)\n    at (wasm://wasm/004f7a76:1:1186270)\n    at (wasm://wasm/004f7a76:1:177689)\n    at (wasm://wasm/004f7a76:1:43502)\n    at (wasm://wasm/004f7a76:1:808077)\n    at (wasm://wasm/004f7a76:1:42895)\n    at (wasm://wasm/004f7a76:1:808077)\n    at (wasm://wasm/004f7a76:1:42895)"}

Ahh I can reproduce. Need to find another way to initialize wasm. My previous fix https://github.com/wei/socialify/pull/230/files did not work. The error changed from "Already initialized. The ``initWasm()`` function can be used only once." to "RuntimeError: unreachable".

Suggestions/PR welcome!

Currently it's imported on the API route

socialify/pages/api/png.ts

Line 4 in 3760dcc

import renderCardPNG from '../../common/renderPNG'

Which imports renderPNG which initializes the wasm at

socialify/common/renderPNG.tsx

Line 3 in 3760dcc

import resvgWasm from '../public/resvg_bg.wasm?module'

Looks like the error only occurs when there are emojis in the description. Let's investigate further in #255 perhaps that will fix the issue here too.

e.g. working without description:
https://socialify.git.ci/octomation/stub/png?description=1&descriptionEditable=Stub+domains+for+redirects.&font=Raleway&language=1&name=1&owner=1&pattern=Circuit%20Board&theme=Light

broken with description that contain emoji:
https://socialify.git.ci/octomation/stub/png?description=1&font=Raleway&language=1&name=1&owner=1&pattern=Circuit%20Board&theme=Light

Fixed in #256 . Will deploy to prod once approved.
