[woctezuma]

The error arose when attempting to create booster packs, because the sessionid cookie could not be found.

To fix this issue, you need to fill in your cookies in personal_info.json, especially sessionid.

Once this is done, you could run the script again after toggling these boolean values to False to save time: https://github.com/woctezuma/steam-market/blob/57c717118fed8c660bd830f51f0ccfaf45fd5e40/market_arbitrage.py#L498-L499

---

That being said, I am surprised that the script could run this far without the cookies.

Did you fill in some of the info, but not all of the info, e.g. steamLoginSecure but not sessionid? 🤔 Indeed, if the sessionid cookie had been available but obsolete, then the error would have been different. Here, it seems that the value of the sessionid cookie was not filled in at all, but some of the rest of the cookies must have been correctly filled in, for the script to run this far.

Interesting.

Then maybe the script updated the cookie values in the JSON file and erased the value of sessionid which you had previously filled in. Not sure how this would be possible. Edit: After looking at the code again, I don't think the dictionary entry for sessionid could be deleted when updating cookies.

Could you check which fields currently exist in the JSON file personal_info.json?

As you see above I didn't fill in the sessionid value because the README file just said I need the value for steamLoginSecure (or maybe I was just blind and didn't see it 😄 )

Ah, I see where the confusion could come from.

Indeed, the README only mentions steamLoginSecure in the section called How to fill-in your cookie information. Based on the run of the script, this seems right: the script worked fine with relaxed rate-limits by solely using the steamLoginSecure cookie, and the script only failed at the very end when it was time to create booster packs.

The sessionid is mentioned a bit below in the README in an annotation (NB²) "to automate the creation and sale of booster packs". So I understand how it could be overlooked.

On a side-note, it is always possible to perform this last step (creation and sale of booster packs) manually by going to this page to create packs, and then manually listing packs on the Steam Market. This is especially relevant if there are only a few packs.
