I saw an other topic having the same problem, but even with deleting the brackets, the error still appears.
I don't understand why does it work correctly with the first flow, but not with the second one ?
I am currently on a Trial version, maybe the use is limited to one flow ?
Is there a parameter (depending on the Sharepoint server) that restrict the use of this loop ? I can't figure out why there is this difference on two identical flows.
Let me know if you have a solution for this.
Thank you for your help ! I finally figured out the problem, which comes from the Get files (properties) action, as you suggested.
Depending on the Sharepoint server, this action must be configured to work correctly :
The real Sharepoint has an important amount of documents, whereas the Test Sharepoint does'nt have that much, so I put the 'Include Nested Items' to "No". Even though I restrict the files to one folder, I must make this configuration.
