javascript error

I tested the integration around two weeks ago and it was working fine.

two questions:
1) is it necessary to update the instagram token regularly? I noticed around two weeks ago tha a working instagram feed suddenly was not working anymore.

2) today I suddenly get a javascript error. The images are there, the grid shows too but empty and in the console I see a JS error. Well, in fact two:
