polymarket clob api error

[Collapsar-q]

I have recently found frequent errors when trading BTC5M, such as trading during times of frequent trading,
post error: API error (500): Failed to post order: {"error":"could not run the execution"}
What's the reason for this? It's occasional

[libaice]

"could not run the execution" error (500) has a few possible root cause

That problem should be caused by the price of the limit order being too far from the market price.

Near window boundaries (last 30-60 seconds), the CLOB gets flooded with last-second orders.

The matching engine accepts your order off-chain but the execution pipeline chokes — hence the 500 rather than a clean rejection.

I am using the 0.99 FOK taker mode. Will this issue be officially resolved 雾中 ***@***.***

@sahilgat02 @fednerpolymarket
i'm getting "could not run the execution" error in as much as 60% of order submission attempts. this started yesterday. you really need to look into this. users using your frontend are having same issues.

I also had up to 60% of orders fail today, and it's getting worse and worse

I have the exact same problem. Updating to py-clob-client2 does not solve it.

I've been experiencing the same issues. As per @libaice potential diagnosis above, I am currently placing limit orders far above the market price (always at 0.99). I am going to change this approach so it's closer to market and will feed back

have same issue on FAK / 0.98

[TimothyBasson]

I reduced mine to place orders close to the market price and still have the same issue. Hopefully this will be fixed when V2 releases
