Aircraft
After being cleared for the visual approach and landing into ZZZ on Runway XX; we continued to configure the aircraft for landing. We proceeded to descend below 3;000 just inside the ZZZZZ fix. As we turned final around 2;600 feet MSL around 1;300 AGL we received a 'Obstacle' GWPS warning which we were given an RA to pull up. I immediately complied with the command until it confirmed and we visually confirmed that we were clear and continued the approach to land without incident. During the incident we did not observe nor did Tower observe any obstacles that we were in close proximity to. We maintained proper clearance of at least 1;000 feet AGL from all of the published towers that were on the approach plate.Cause - There were no noted obstacles that were within 1;000 feet AGL clearance and can only come to the conclusion that it was an anomaly with the GWPS system.  At 2;800 feet we had turned inside the Tower that was 1;740 feet and turned well before the Tower at 1;809 maintain safe and legal separation from structures.Suggestions - Continue to follow protocol and respect a Resolution Advisory.
EMB-175 Captain reported receiving an Obstacle GWPS warning followed by a 'Pull up' RA command during a visual approach; which was followed by the crew.  The Captain stated it was most likely a GPWS anomaly that triggered the warnings as no problem obstacles were noted.
