It's obviously the incorrect type, while our CI didn't catch it, Nicholas did:

plugins/fetchinvoice.c:1362:30: error: conversion from 'long long unsigned int' to 'size_t' {aka 'unsigned int'} changes value from '18446744073709551615' to '4294967295' [-Werror=overflow]
 1362 |      || tlv_span(wire, 1001, UINT64_MAX, NULL) != 0) {

I see your CI is building ARM32, so this is strange it didn't detected the problem.
I would suggest that you try to build the contrib docker files as part of CI. Not only it would have caught that, but it would also avoid getting out of date dockerfiles.
