stream-frame | a stream framing library for node.js | Runtime Evironment library

I'm running across an extremely strange bug while using GetStream: i'm running a script to migrate over 200k activities (previously used an internal stream-framework fork) and I'm running across a really bizarre issue.

The problem is this: I'm setting the 'time' field to a custom value (usually in the past). Now: these activities are being ordered wrong by the API.

Although the activities being added have correct, ISO8601 UTC times in the past, the oldest ones are coming back on top of the feed (mixed with only a couple of new activities).

This is really odd and I'm at the end of my wits -- this seems like an issue on Stream's end.

Thoughts? Below is a screenshot of the issue.

I'm currently working on a website, which triggers a net::ERR_HTTP2_PROTOCOL_ERROR 200 error on Google Chrome. I'm not sure exactly what can provoke this error, I just noticed it pops out only when accessing the website in HTTPS. I can't be 100% sure it is related, but it looks like it prevents javascript to be executed properly.

For instance, the following scenario happens :

1. I'm accessing the website in HTTPS

2. My Twitter feed integrated via https://publish.twitter.com isn't loaded at all

3. I can notice in the console the ERR_HTTP2_PROTOCOL_ERROR

4. If I remove the code to load the Twitter feed, the error remains

5. If I access the website in HTTP, the Twitter feed appears and the error disappears

Google Chrome is the only web browser triggering the error: it works well on both Edge and Firefox. (NB: I tried with Safari, and I have a similar kcferrordomaincfnetwork 303 error)

I was wondering if it could be related to the header returned by the server since there is this '200' mention in the error, and a 404 / 500 page isn't triggering anything.

Thing is the error isn't documented at all. Google search gives me very few results. Moreover, I noticed it appears on very recent Google Chrome releases; the error doesn't pop on v.64.X, but it does on v.75+ (regardless of the OS; I'm working on Mac tho).

Any clue at this point to investigate would be gladly appreciated !

Thanks in advance.

Edit 1 : Might be related to Website OK on Firefox but not on Safari (kCFErrorDomainCFNetwork error 303) neither Chrome (net::ERR_SPDY_PROTOCOL_ERROR)

Edit 2 : Findings from further investigations are the following :

• error doesn't pop on the exact same page if server returns 404 instead of 2XX
• error doesn't pop on local with a HTTPS certificate
• error pops on a different server (both are OVH's), which uses a different certificate
• error pops no matter what PHP version is used, from 5.6 to 7.3 (framework used : Cakephp 2.10)

Edit 3 : As requested, below is the returned header for the failing ressource, which is the whole web page. Even if the error is triggering on each page having a HTTP header 200, those pages are always loading on client's browser, but sometimes an element is missing (in my exemple, the external Twitter feed). Every other asset on the Network tab has a success return, except the whole document itself.

Google Chrome header (with error) :

Firefox header (without error) :

A curl --head --http2 request in console returns the following success :

I know that browsers can send RST_STREAM-frames to cancel serverpush.

Does it make sense to send Last-Modified or Etag headers inside the PUSH_PROMISE? Or is the validation of the to-be-pushed resources only based on their URI (as Simone Bordet answered to the following question two years ago)?

Does the browser cancel server push when a resource is in cache?

I couldn't find an exact answer to this question.

How can I tweak stream-framework to make it use postgreSQL instead of Redis
