Hey,
the payload itself looks correct. The only problem is the order of the coordinates in the geometry or the bbox parameter.
If you know that the geometry is correct, then just change the order of latitude and longitude of the bbox.
bbox: c0_0, c0_1, c1_0, c1_1
=>
bbox: c0_1, c0_0, c1_1, c1_0
If you know that the bbox is correct, change the order in the geometry.
geometry: POLYGON ((c0_0 c0_1, c_1_0 c1_1, c2_0 c2_1, c3_0 c3_1, c4_0 c4_1))
=>
geometry: POLYGON ((c0_1 c0_0, c_1_1 c1_0, c2_1 c2_0, c3_1 c3_0, c4_1 c4_0))
