Hello, hard to say without a way to reproduce. Can you find a reproducer? How your data looks like? What is the size of it? Also, please provide server configuration.

Hi @FZambia
Here is my server configuration
{

"debug": true,
"token_hmac_secret_key": "xxx",
"admin_password": "xxx",
"admin_secret": "xxx",
"api_key": "xxx",

}

It seem that i am getting error when receive delta change message from mkt channel. I will try to get a way to reproduce it and update u soon. Tks

Thx! I have an idea what could be the problem, will come with a possible fix very soon. In the meanwhile, if you find a reproducer – will be a great help. Some insights about data size is also helpful - as I think it may be related.

[FZambia]

@maithanhtan could you please try 5.2.2 – I believe it should fix the exception. Though a bit shot in the dark since there was no reproducer.

[FZambia]

@maithanhtan hello, did you have a chance to try?

Please re-open if the issue persists with 5.2.2
