A pattern observed for this error is, the paragraph has reference which is a template and that it contains an image.

Setting high priority since https://en.wikipedia.org/wiki/Template:Source-attribution or https://en.wikipedia.org/wiki/Template:PD-notice is used very frequently in references for English wiki. If any paragraph has such references, MT is failing for all MT engines.

There is no error in the console, but the references are not properly adapted. They are shown as empty references (rendered in grey) when they are not empty. This may cause publishing to skip them. The expected result would be for these references to be rendered in blue instead as regular references.

This may be a regression of T225716, or a case not covered by it.

I checked this and this is an unrelated issue: T301952: For references with multiple templates, the calculation of overall adaptation status is wrong

Great! Thanks @santhosh
