ERROR 6: Unrecognizable band number (None)

How did you install ODM? (Docker, installer, natively, ...)?

Docker

What is the problem?

While running WebODM with DJI Multispectral M3M, I got this :

So WebODM generates a good orthophoto but fails to create report using generate_png function when using DJI M3M

What should be the expected behavior? If this is a feature request, please describe in detail the changes you think should be made to the code, citing files and lines where changes should be made, if possible.

Succeed to generate report when using DJI M3M

How can we reproduce this? What steps did you do to trigger the problem? If this is an issue with processing a dataset, YOU MUST include a copy of your dataset AND task output log, uploaded on Google Drive or Dropbox (otherwise we cannot reproduce this).

Try to generate report with M3M dataset

Thanks for the report, but it looks like you didn't include a copy of your dataset for us to reproduce this issue? Please make sure to follow our issue guidelines 🙏
