Retrying internal errors in files_upload_v2

Hi there,

We occasionally see transient errors from the Slack API in calls to files.completeUploadExternal that are done within the SDK's implementation of files_upload_v2. The error we see most frequently error we encounter is file_update_failed, which has more or less no useful explanation on the API docs. Support has also not been very helpful in understanding the nature of these issues: they just said there is a temporary server error, and we should retry the call to completeUploadExternal

Can the Python SDK implement that retr? It doesn't seem like the caller of files_upload_v2 (i.e. our code) could, since that would redo the entire upload. The caller also doesn't have enough information to retry the files.completeUploadExternal call, since the ID is lost when the SDK throws an exception.

I suppose a workaround is to install a custom RetryHandler on the WebClient. But like in #1715, shouldn't that just be part of the SDK?

Inizia dall’implementazione di WebClient.files_upload_v2 del Python SDK e segui la sua chiamata a files.completeUploadExternal. Determina come sia possibile ritentare gli errori interni transitori, come file_update_failed, senza ripetere l’upload, quindi verifica che l’upload completato abbia ancora esito positivo tramite il punto di ingresso esistente di WebClient.
