re. metadata query for DE panel is wrongly generated w/ an empty dim member
In prod design the dataflow doesn't display any metadata for the dataflow OECD.SDD.NAD:DSD_NAMAIN10@DF_TABLE1_EXPENDITURE(1.0). When clicking on the i icon next to the dataflow header in https://data-explorer.oecd.org/vis?lc=en&df[ds]=Design&df[id]=DSD_NAMAIN10%40DF_TABLE1_EXPENDITURE&df[ag]=OECD.SDD.NAD&df[vs]=1.0&av=true&pd=%2C&dq=A.AUS.......XDC.V..&ly[rw]=TRANSACTION%2CSECTOR%2CINSTR_ASSET&ly[cl]=TIME_PERIOD&to[TIME_PERIOD]=false&lo=5&lom=LASTNPERIODS&vw=tb, an empty metadata panel is displayed and the query in the background returns the 422 (Unprocessable Entity) error (key parameter value '' doesn't comply with the value pattern '^(*|\S+)$').
In rest v2 queries you cannot have empty dim members in the key param, so this metadata query is wrongly generated (the same query with * everywhere does not throw this error):

Reproduce in qa:stable with the same ref. metadata that was uploaded some weeks ago:
