Unterminated quoted string at or near \“'\\' ORDER BY \”id\“\”" when using loopback connected to pos

[M504 Mm]

When I using like filter in loopback restful api, it return the following error.

"name":"error","status":500,"message":"unterminated quoted string at or near \"'\\' ORDER BY \"id\"\""

However, when I remove the primary key setting in postgresql, the error is gone. Do it mean the primary key makes this error?
