I have come across the same issue when I try to pull requests from the GitHub. In order to resolve that, I have made some changes in that view and perform the commit and push operation over that view.
To get more information about error, I would modify the Virtual DataPort log level as “Debug’’ in <DENODO_HOME>/conf/vdp/log4j2 and check for the possible causes in the vdp.log file in <DENODO_HOME>/logs/vdp.
For more information, you could refer to the section [Log Configuration](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/appendix/configuring_the_logging_engine/configuring_the_logging_engine) of the Virtual DataPort Administration Guide.
Hope this helps!
