Error 999999 when doing join field in model builder

[ClaudiaCaceres4]

I am trying to do a simple join of five tables in a geodatabase. Afterwards I create a xy layer event after all the tables are joined. I tried it one time and it worked fine. I erased the resulting shapefile and added more steps into my process but now when I try it again the join process is not working. I get an ERROR 999999: Error executing function. General function failure Too many fields defined. Failed to execute (Join Field).

I tried checking the log to see what was the specific error but the log for today is empty. Can someone please help me.

Try deleting the intermediate data of the model manually. To manually delete intermediate data after running a model in the ModelBuilder window, click Model menu > Delete Intermediate Data.

Try running the model again.
