Temporary 502 error #58

Open bpinsard opened 2 months ago

bpinsard commented 2 months ago

What happened?

I am trying to pull large results (69 pages of 1000 results) from the API, I sometimes have to retry 5 times to not get a 502 (Bad Gateway) error from nginx. Is it caused by the query being too large and python timing-out on nginx? Is there a recommend number of results to pull in a page?

What command did you use?

Something like

curl https://mriqc.nimh.nih.gov/api/v1/bold?max_results=1000&where={"bids_meta.MagneticFieldStrength":3,"bids_meta.MultibandAccelerationFactor":4,"bids_meta.RepetitionTime":{"$lt":1.6,"$gt":1.4},"spacing_x":{"$lte":2.2,"$gte":1.8},"spacing_y":{"$lte":2.2,"$gte":1.8},"spacing_z":{"$lte":2.2,"$gte":1.8},"size_t":{"$gte":100}}&page=9

Also for context, I am re-running a code that managed to pull the same query 2y ago without issues IIRC.
