Base64 decode leads to partial decode followed by non printable characters

We are trying to decode base64 encoded strings from some scraped URLs. However the decoding works only partially and starts generating non-printable characters. For example,

Here is the encoded string

CiQ2MmE5NzI5NC01YTJhLTQzMTctOTU2Yi1lY2E3MjU3NzA2ZWEQyIgCGISAAiIDQ1BBKM609E8whIACOZhn42doAQAAQg10X3NyeGhsODZ2emxnSgJJRFIGQ2hyb21lWgxNb2JpbGUgUGhvbmViB0FuZHJvaWRqeGh0dHBzOi8vcmV2dHRtb2JpbGUuY29tL2NsaWNrLnBocD9rZXk9ZGEyZ3luNGc3bnZtanM4MDk0YWEmQ1BDPXtDUEN9JkNBTVBBSUdOX0lEPXtDQU1QQUlHTl9JRH0mQ1JFQVRJVkVfSUQ9e0NSRUFUSVZFX0lEfXIeCMaUMxD29gEYosk_IPb2ASgAMgYwLjAwNzBAAEgigAGIrpGwB4gB-o7B4wWSAQ8xMTguMTM2LjE1NC4yMjaaAQ8xMTguMTM2LjE1NC4yMjaiAQxKYWthcnRhIFJheWE=

the decoded output looks like this

So we are able to get partial data but not everything. Any ideas on why this is happening?
