Getting error after clicking next to see Map to item fields tab with Custom JSON data loader

Hi all, I created and tested a custom JSON data loader with CLI and everything works well. I uploaded the loader to test in UI but I get an error in the browsers preview request’s response. I checked my mappings.json file and other settings. but everything look well. Is there any log file to check errors for this situation?

Through the Top Right dropdown Menu, under Server,

you can find the logs when clicking on Log Files in the left panel.

I encountered this same issue.
“In the tutorial, as well as the samples and templates on the Squirro Github page: batch_size and self.args.source_batch_size are used separately even though they are the same. self.args.load_batch_size is what should be used instead of batch_size in getDataBatch. Except, this argument seems to be broken as a 404 is raised when the loader attempts to pull the schema or sample data.”

In the end I used (and clamped) batch_size. The tutorials/samples need to be updated to better explain and use these args.

Thank you for flagging this Jonathan - we will look at the samples and updated them where required. :rocket:
