https://community.blueprism.com/t5/Product-Forum/Control-Room-error/m-p/54684#M9161 Hello, I have a simple object which performs an action similar to a vlookup on a collection. When I run this in debug mode (in studio) it works perfectly on at least 5 different computers tested. However when this is run in control room, 2 of them terminate throwing the error "ERROR: Internal : Could not run the object because one of the code stages has a compile error, use Check for Errors for a list of problems". Anyone have any ideas why?

Are there any code stages that point to references, and could those references be missing on the 2 other machines? Do they fail every time?

References can't be missing as they all run fine in debug/studio, and show 0 errors at both the object and process levels. Yet somehow fail on the same machine when ran in control room.

Here is my issue in detail : I have a process that utilizes the Utility – JSON VBO object to convert a collection to JSON. The process work beautifully if I run it manually. It also works beautifully if I run in from Control Room manually (under Session management). However, it FAILS when I schedule the process and it runs using a run time instance of Blue Prism on the same machine.   I’ve tested many different collections and it always fails on this conversion.   The error that pops up is not very useful: ERROR: Internal : Could not run the object because one of the code stages has a compile error, use Check for Errors for a list of problems Wed, 27 Jun 2018 20:56:00 GMT https://community.blueprism.com/t5/Product-Forum/Control-Room-error/m-p/54687#M9164 SaurabhKumar1 2018-06-27T20:56:00Z https://community.blueprism.com/t5/Product-Forum/Control-Room-error/m-p/54688#M9165 Hmm, strange. I don't doubt what you're seeing guys but it shouldn't happen - Studio and Control Room are executing the same process/objects. All I can suggest is to contact the Support team.

Did any one got a resolution on this Thu, 28 Jun 2018 12:09:00 GMT https://community.blueprism.com/t5/Product-Forum/Control-Room-error/m-p/54689#M9166 ArjunRaj 2018-06-28T12:09:00Z https://community.blueprism.com/t5/Product-Forum/Control-Room-error/m-p/54690#M9167 I also have this error during runtime and have no idea why. Any help or insight would be appreciated!

It seems like the bot is losing references to the dll over time.
