The basic mergeE was:

javascriptconst 
mergeEMap = new Map();
mergeEMap.set(t.id, "teste-edge");
mergeEMap.set(t.label, "edge-label");
mergeEMap.set(direction.from_, "test-vertex");
mergeEMap.set(direction.to, "test-vertex2");
await g.mergeE(mergeEMap).iterate();

javascriptconst 
mergeEMap = new Map();
mergeEMap.set(t.id, "teste-edge");
mergeEMap.set(t.label, "edge-label");
mergeEMap.set(direction.from_, "test-vertex");
mergeEMap.set(direction.to, "test-vertex2");
await g.mergeE(mergeEMap).iterate();

javascriptconst 
mergeEMap = new Map();
mergeEMap.set(t.id, "teste-edge");
mergeEMap.set(t.label, "edge-label");
mergeEMap.set(direction.from_, "test-vertex");
mergeEMap.set(direction.to, "test-vertex2");
await g.mergeE(mergeEMap).iterate();

javascriptconst 
mergeEMap = new Map();
mergeEMap.set(t.id, "teste-edge");
mergeEMap.set(t.label, "edge-label");
mergeEMap.set(direction.from_, "test-vertex");
mergeEMap.set(direction.to, "test-vertex2");
await g.mergeE(mergeEMap).iterate();

Doing the same in a jupyter notebook just works proving that vertexes exists for example

g.mergeE([(T.id): 'teste-edge', (T.label): 'edge-label', (Direction.from): 'test-vertex', (Direction.to): 'test-vertex2'])

g.mergeE([(T.id): 'teste-edge', (T.label): 'edge-label', (Direction.from): 'test-vertex', (Direction.to): 'test-vertex2'])

g.mergeE([(T.id): 'teste-edge', (T.label): 'edge-label', (Direction.from): 'test-vertex', (Direction.to): 'test-vertex2'])

g.mergeE([(T.id): 'teste-edge', (T.label): 'edge-label', (Direction.from): 'test-vertex', (Direction.to): 'test-vertex2'])

mergeV is working as expected

Anyone have the same problem or had the same issue that could help me on that matter?
