When trying to getDocument I occasionally encounter "unable to get issuer certificate"

Sometimes I am sending a series of getDocument requests using Node.js SDK and sometimes I get an error: unable to get issuer certificate

Example ^

The not found error is what I mark explicitly in my logs.

Are there rate limits for getDocument ?

I also get this for trying to creat a document

I run these queries in parallel, so at any time, a dozen of requests can be sent a second.

Since there's no bulk upsert facility

Using await Promise.all()

When attempting to send database calls in a sequential order, it works fine. It seems like there's some hidden rate limit. If someone from the Appwrite team could answer, I'd be very happy.

When working with hundreds or thousands of records per minute, not using parallelisation is causing a performance bottleneck.
