LPCLOUD HLS status code 400

[RichardScottOZ]

Yesterday at one stage I was getting the above error

stac_items = Search(url='https://cmr.earthdata.nasa.gov/stac/LPCLOUD',
                 collections=['HLSL30.v1.5'], 
                 #bbox = '-53.0172669999999968,-9.5331669999999988,-48.4956669999999974,-3.1035670000000000' ,
                 bbox = '-53.0232820986343754,-8.1236837545427090, -49.4688521093868800,-4.8677173521785928',
                 datetime='2016-04-23/2021-04-23', 
                ).items()

 File "stackstac_NASA_HLS_cropped.py", line 119, in <module>
    stac_items = Search(url='https://cmr.earthdata.nasa.gov/stac/LPCLOUD',
  File "C:\Users\rscott\AppData\Local\Continuum\anaconda3\envs\stackstac\lib\site-packages\satsearch\search.py", line 90, in items
    found = self.found(headers=headers)
  File "C:\Users\rscott\AppData\Local\Continuum\anaconda3\envs\stackstac\lib\site-packages\satsearch\search.py", line 62, in found
    results = self.query(url=url, headers=headers, **kwargs)
  File "C:\Users\rscott\AppData\Local\Continuum\anaconda3\envs\stackstac\lib\site-packages\satsearch\search.py", line 80, in query
    raise SatSearchError(response.text)
satsearch.search.SatSearchError: "Request failed with status code 400"

and then it worked, then it stopped working again.

Some sort of rate limiting or something along those lines perhaps?

@RichardScottOZ I've encountered these errors occasionally as well, and this could be due to some inefficiencies in CMR queries. Will look more into it, thanks.

BTW @RichardScottOZ, there's a replacement for sat-search now - https://github.com/stac-utils/pystac-client that currently replicates most everything sat-search does, with more functionality coming in the next few months.

[RichardScottOZ]

Thanks will give that a try shortly.

I believe this issue should be fixed, by limiting the max items returned per page, and also internally reducing the number of calls to CMR.

Please open up a new issue if you find there is still an issue here.

Thanks Matthew, hopefully give this a shot in the next few days.
