I have a public actor and some of my users experience that either default and/or named datasets don't seem to be existing and somehow won't be created when pushing data to them. This is the error message I can see affecting only a handful of user runs:

bash

How can I ensure that the datasets are created ahead of time when running the scraper before it collects data and then fails because the dataset cant be created or does not exist?

Someone will reply to you shortly. In the meantime, this might help:

Hi @Casper, can you send me some Id of the Run when the problem happened, so we can investigate?

I have just sent you them now

Hi @Casper does the issue still occurs? Based on the logs it really seems that there is an attempt to push data into non-existing Dataset, can you share code when where you handle managing the datasets and pushing the items into them?

@Pepa J I can give you access to the git repository to make it easier to troubleshoot. Just send me your github username in a DM 🙂 The issue only happens to a subset of customer runs.

@Casper The code looks good. I was trying to reproduce it, but unsuccessfully. Does it happen often? Would you be able to put together minimal code example of such a behavior?
