This error could be the result of a number of things. I noticed you already submitted a request to support. Our Server team will be able to help you!
Indeed I'm now waiting for support answer.
To be more precise :
- the errors occurs since we migrated from v7 to v8
- the errors occurs with workbooks:
- available on Serverv7 before migration, and so migrated automatically to v8
- we reimported on Desktop v8 to update,
- first time we reexported from Desktop v8 to Server v8 => ok
- second time we reexported from Desktop v8 to Server v8 => error 500
The case is reproduced with all our workbooks created on v7.
Thanks for your help,
