I want to use the class lib in an ad hoc data source, but get an Assembly not found error when using it in my Low code app.
Linking rows to DataMiner objects | DataMiner Docs
How do I get this to work?
What did I forget?
DataMiner 10.5.5.0-15664 and useDxM is enabled

Validating the Automation script in Cube results in 0 errors.
Restarting browser results in the same assembly error.
I've checked the protocolscripts folder and the dlls is available on the system.
System only has 1 agent. so no sync issue.
Turns out it is not allowed to have library name with dots in.
I had a Data source using xxx.yyy.zzz as lib name in the XML definition.
replacing it to xxx_yyy_zzz solved the problem.
Compiling a C# code block as a library | DataMiner Docs
<Param type="libraryName">xxx_yyy_zzz</Param>
I'm currently doing the exact same method and it seems to be working. One thing I noticed is that in some cases, the code is incorrectly cached, and errors like the one you have start popping up. If you are sure that the Data Source has no errors, can you try a browser restart?
