Error with the upload of data at the create collection step

Since few weeks, we have some difficulties to upload the both mzML and mzXML. Each time there is one file with an error and this is never the same. The issue is that this error appears only once we created the collection.
Thanks in advance for your help
Best, Nicolas

@team.galaxy any ideas ?

Galaxy error I think, maybe better now

Nicolas is it ok now?

Thanks for your reply @dbenaben and @yguitton and sorry late one.
It works better now. In between, I found a "solution" that consisted to import all the mzML as single files and then create the collection.
Best, Nicolas
