ValueError: Illegal format `object` at astrodrizzle.AstroDrizzle step

[Shalmalee15]

Hi. I am sorry if this error is already dealt with, but I could not find a solution which could solve my problem. Thanks in advance. astrodrizzle.log

I am trying to align two sets of HST images from two different cameras; ACS and WFC3. I am getting following error for the step of astrodrizzle.AstroDrizzle('input_0?_flt.fits', and other parameters).

This is the first time I received this error. Prior to this, I had successfully aligned all the images using drizzlepac for a different set of images, but now I am stuck at this step for this image set. I should also mention that I recently reinstalled my (Ubuntu) system, installed Anaconda3 and created the AstroConda, iraf27 environments with python 2.7. Are there any library dependencies I need to install in order to solve this? Any suggestions, please? Thank you so much.

I have attached a google link where I have uploaded the log files, and fits images. https://drive.google.com/drive/folders/1rFjSywSO6zk2nvLKKQancb3C9HqTCXBf?usp=sharing
