Flow suddenly failing

[luisarodriguez]

Hi!

I have a very simple approval flow that has been working fine for the last months, today I suddenly got this error:

Http request failed: the content was not a valid JSON. Error while parsing JSON: 'Unexpected character encountered while parsing value: R. Path '', line 0, position 0.'

Not sure what is happening as the flow hasn't been modified 

Could you please assist?
