# What to do if an Assembly Step hasn’t produced any results? Please double check the following: * Is your Step'sRobot able to deal with the file you are providing it with? The video related robots, for example, will ignore all files except videos. * Does the Step referenced in yourStep's `use` parameter produce any result? Are you sure that your Step actually has some input? * If the result of your Step is passed into a subsequent Step, it will not produce a result by default. You can add `result: true` to your Step to force the creation of a result in this case. ## See also: [What happens if my plan limit is reached?](/docs/faq/plan-limit-reached.md) [What are Collaboration Seats?](/docs/faq/collaboration-seats.md) [How does Transloadit store Assemblies?](/docs/faq/how-we-store-assemblies.md)
