Please how can i overcome this issue

[smfcrts]

@lnicola please could you give a solution to this issue

[lnicola]

@smfcrts sorry for the late reply. Can you tell us what version of the system you are running and maybe attach a copy of that HDR file?

[smfcrts]

Hello,
The version of the system is 2.0.1, and find below example of the HDR file(I changed here
S2A_OPER_SSC_L2VALD_29SMS____20190813.txt
the extension to .txt because i can't upload HDR file):
Uploading S2A_OPER_SSC_L2VALD_29SMS____20190813.txt…

[smfcrts]

@lnicola I sent a copy of attached HDR file,please have a look on it

[lnicola]

I'll think about it when I find some time, but I didn't see anything obviously wrong there.

[smfcrts]

Thank you @lnicola

[smfcrts]

@lnicola Hi, did you have a look on the HDR file, because i still have the same problem even if the L2A products are well generated.

[lnicola]

I couldn't see anything obviously wrong with the file. Can you upload the whole product somewhere (e.g. https://send.firefox.com) so I can pass it to my colleague who knows more about the L3A?

In the meanwhile, can you test with fewer input products in that command line? Even a single one, if it allows you. Also, what happens if you remove the first product from that list? Do you get an error on the second one as well?

[smfcrts]

I tested with only one product and it give the same error, and even if i remove the first one it give error on the second one. So which product should i upload?

[lnicola]

Either of them, I suppose.

[smfcrts]

Do you think it could be a problem of permission?

[lnicola]

It might be. Does cat /mnt/archive/maccs_def/morocco/l2a/S2A_MSIL2A_20190813T112121_N0208_R037_T29SMS_20190813T114617.SAFE/S2A_OPER_SSC_L2VALD_29SMS____20190813.HDR work from the account you're using to run the processor?

[smfcrts]

ok i'll try, what does cat do?

[lnicola]

It should display the contents of that file (it's an XML) to the console/screen. If you get a "Permission denied" error, it means it's not working.

[smfcrts]

yes it works.
