When running mpc with custom data, I get 500 error and error in log

Worked before upgrade
Try setting COIN_CMD on lp_solver, and path to /usr/bin/cbc. (If haven't already)
I have noticed pulp having a few issues. changed armhf and arm/7 to COIN_CMD to fix theirs.
If this fixes it we may need to do the same on amd64. Although when testing I didn't notice any issues myself.
These are already set this way
mmm. could you test lp_solver to PULP_CBC_CMD and default and path to empty
tested with MPC with this: (just changed the single quotation marks to double)

} "lp_solver": "COIN_CMD",
"lp_solver_path": "/usr/bin/cbc",Seemed to work on my amd64. Might be good to see if uninstalling it and reinstalling works? Ill do some more testing and see if I can replicate the issue.
Edit: So far I cant replicate the issue sorry. May be also good to see if resetting the configuration parameters to their defaults (I.e. a fresh install) then running MPC causes any change.
setting to PULP_CBC_CMD and empty worked
setting to PULP_CBC_CMD and empty worked
Thanks for that. We should keep an eye open and see if other people have the same issue. @davidusb-geek
Closing as solved
