Memory access out of bounds

[maxdeichmann]

I am using tiktoken in my project here: https://github.com/langfuse/langfuse/blob/250a5b03d2068774151757d8a0b33115a56243e2/src/features/ingest/lib/usage.ts#L6

As advised in the docs, i always free up the encoder, after usage. Sometimes, i use the same encoder multiple times without freeing it in between encode() function calls. Is this an issue?

I am running a nextjs project, and configured everything as required:https://github.com/langfuse/langfuse/blob/250a5b03d2068774151757d8a0b33115a56243e2/next.config.mjs#L60

My exact exception is the following:

hi @maxdeichmann , did you ever resolve this issue?

I switched to TikToken-JS which works much better
