"(An unexpected error has occurred (#100)"

[Rajnish_Pandey1 (Rajnish Pandey)]

Hi All,

I am working in an RPA project and we were deploying a package to the orchestrator but were getting the error “(An unexpected error has occurred (#100)”.

We tried different environment but still getting same error.

Hi @Rajnish_Pandey1 ,
The “An unexpected error has occurred (#100)” usually points to an issue with the package itself — could be corrupt, too large, or missing dependencies.

Try these steps:

• Rebuild the package from Studio
• Make sure all dependencies are properly restored
• Check if the .nupkg size is too large
• If still failing, try uploading it manually via Orchestrator
• Also, check Orchestrator logs for more details

Also you can refer the bellow:

An unexpected error has occurred (#100)”

Hi @Rajnish_Pandey1

Could you please confirm if this issue is happening for any other package as well or just this one?

If its only with this package, then issue may be with the package.

If package is more than 30 mb, then also you may face this error. if package size is fine, but still facing issue, i would suggest to repackage it and then try.

Also, have you tried deploying the package to orchestrator directly via studio?

It would be worth checking your permissions as well if you have one to upload tenant level packages?
