Unexpected token < in JSON at position 0 when viewing the form

Dear Support team.

I have tried to upload the XLS Form in the Kobo collect but failed to do so and it appears a message saying “Unexpected token < in JSON at position 0”
Would anyone please help me with this technical issue?

Best regards,
