[BUG] spanner queries give KeyError if spanner_config not set via register() #644
Description
Describe the bug
if spanner_config not set, spanner_gql_to_g and likely spanner_query_to_df errors out. Need to handle better with error message on how to resolve vs python KeyError
To Reproduce
attempt to run a query without passing spanner_config to register:
g = graphistry.spanner_gql_to_g(query)Expected behavior
Should give descriptive error and how to set with register vs KeyError
Actual behavior
