Cannot upload advancement file form third party application - receive error message

I cannot upload an advancement file from a third party application. I receive the following error message: Invalid memberID: 133584839

The file is the correct type to be uploaded.

that means a MID is bad in the file - are you with the Pack? this scout is not registered in pack anymore - they are in Troop @BrianLawton

Thank you. I am with the Pack. I took over the committee chair function and they must have not uploaded advancements at the end of last year. I will edit accordingly.
