Urgent: Unable to load custom PDB RFDiffusion

[sbhakat]

I am trying to upload the PDB (link: https://www.dropbox.com/s/koxlbk5ntgzzlv6/protchain1.pdb?dl=0) which only has chain A in the RF Diffusion Colab but I am getting the following error:

7ki0.pdb(chemical/x-pdb) - 264951 bytes, last modified: n/a - 0% done

    104       return reply.get('data', None)

MessageError: RangeError: Maximum call stack size exceeded.

The code-snippet corresponding the selection is following

contigs = "A:30" #@param {type:"string"}
pdb = "" #@param {type:"string"}

I am really stuck, any help to debug this error will be highly appreciated?
