The database does not contain location information for this node (NodeDoc.locations is empty).

Further investigation required:

• are there more nodes without location information?
• debug location analysis logic for this node

Node with routes:

• https://knooppuntnet.nl/en/analysis/node/1743067730
• https://knooppuntnet.nl/en/analysis/node/267183476
• https://knooppuntnet.nl/en/analysis/node/271047570
• https://knooppuntnet.nl/en/analysis/node/301387377

Node without route:

• https://knooppuntnet.nl/en/analysis/node/270619038
• https://knooppuntnet.nl/en/analysis/node/2334919075
• https://knooppuntnet.nl/en/analysis/node/9894640978

Probably more.
Some nodes were created in the same changeset

It seem that all nodes in Pertuis get an error 500

I could select La Bastidonne or Ansouis in Explore by location

…but I can't with Pertuis
