Set undirected relationship

I want to design the graph in memory for training the link prediction algorithm, but undirected relationships are required. when I design the graph I use several nodes and several relationships and I try to set them Undirected .

CALL gds.graph.project('myGraph',
['YCHTC','YCHTCp'],
['DETERMINE', 'SIMILAR']:
{ orientation: 'UNDIRECTED' })
YIELD
graphName AS graph, nodeProjection, nodeCount AS nodes, relationshipCount AS rels

But there is an error:

Invalid input '{': expected an identifier (line 4, column 3 (offset: 84))
" { orientation: 'UNDIRECTED' })".

I tried several options, but they are all wrong.

CALL gds.graph.project('myGraph',
['YCHTC','YCHTCp'],
[DETERMINE:{ orientation: 'UNDIRECTED'}, SIMILAR: { orientation: 'UNDIRECTED' }]
YIELD
graphName AS graph, nodeProjection, nodeCount AS nodes, relationshipCount AS rels

CALL gds.graph.project('myGraph',
'*',
{ALL:{orientation:'UNDIRECTED',
type: ' * ' }})
This works, but does not find the properties.

Hi Ion Ganea,
one solution of your problem is to use a map to input your relationship projections instead of a list. Also pay attention to the single quotation marks which are missing for the relationship types in the map:

CALL gds.graph.project(
'myGraph',
['YCHTC','YCHTCp'],
{DETERMINE: {orientation: 'UNDIRECTED'} , SIMILAR: {orientation: 'UNDIRECTED'}})
YIELD
graphName AS graph, nodeProjection, nodeCount AS nodes, relationshipCount AS rels
