Error when using nhd.byids("COMID", main.index.tolist()) (River Elevation and Cross-Section example)

[LucRSquared]

What happened:
I'm just trying to run the example notebook "River Elevation and Cross-Section"

I got an error at cell 13 when trying to query the flowlines by COMID

I get a JSONDecodeError

Minimal Complete Verifiable Example:
This simple code produces the same error:

nhd = NHD("flowline_mr")
main_nhd = nhd.byids('COMID',['1722317'])

Environment:

Output of pynhd.show_versions()

It sounds like when you ran the notebook the NHD web service that the NHD class uses was down. I just reran the notebook and it worked just fine.

You can see that the function throws ServiceError exception (below JSONDecodeError) which indicates that service is not working.

By the way, other than the NHD class you can also use WaterData class to get the medium-res flowlines.

Thank you! I just retried and it worked. Thanks for the WaterData tip! I'm closing the issue.
