Load avro export from BigQuery

[MMH]

I would like to load avro export from BigQuery. Ideally without making any changes to that file. File has the following content:

Obj
avro.codecnullavro.schemaØ {"type":"record","name":"Root","fields":[{"name":"id","type":["null","long"]},{"name":"info","type":["null",{"type":"record","namespace":"root","name":"Info","fields":[{"name":"first_name","type":["null","string"]},{"name":"last_name","type":["null","string"]},{"name":"address","type":["null",{"type":"record","namespace":"root.info","name":"Address","fields":[{"name":"address_street","type":["null","string"]},{"name":"address_street_num","type":["null","string"]},{"name":"address_zip_code","type":["null","long"]},{"name":"address_city","type":["null","string"]}]}]}]}]},{"name":"degree","type":["null","string"]}]} *í½€ðf£šxT[&دÌ/

I pointed fo this file in schema_uri parameter.
When lauched Logstash pipeline I received the following error:

[2019-09-24T13:29:53,589][ERROR][logstash.agent ] Failed to execute action {:action=>LogStash::PipelineAction::Create/pipeline_id:main, :exception=>"MultiJson::ParseError", :message=>"invalid byte sequence in UTF-8", :backtrace=>["C:/logstash-7.3.2/vendor/bundle/jruby/2.5.0/gems/jrjackson-0.4.9-java/lib/jrjackson/jrjackson.rb:91:in `is_time_string?'", "C:/logstash-7.3.2/vendor/bundle/jruby/2.5.0/gems/jrjackson-0.4.9-java/lib/jrjackson/jrjackson.rb:36:in `load'", "C:/logstash-7.3.2/vendor/bundle/jruby/2.5.0/gems/multi_json-1.13.1/lib/multi_json/adapters/jr_jackson.rb:11:in `load'", "C:/logstash-7.3.2/vendor/bundle/jruby/2.5.0/gems/multi_json-1.13.1/lib/multi_json/adapter.rb:21:in `load'", "C:/logstash-7.3.2/vendor/bundle/jruby/2.5.0/gems/multi_json-1.13.1/lib/multi_json.rb:122:in `load'", "C:/logstash-7.3.2/vendor/bundle/jruby/2.5.0/gems/avro-1.9.0/lib/avro/schema.rb:38:in `parse'", "C:/logstash-7.3.2/vendor/bundle/jruby/2.5.0/gems/logstash-codec-avro-3.2.3-java/lib/logstash/codecs/avro.rb:69:in `register'", "C:/logstash-7.3.2/logstash-core/lib/logstash/codecs/base.rb:18:in `initialize'", "org/logstash/plugins/PluginFactoryExt.java:258:in `plugin'", "org/logstash/execution/JavaBasePipelineExt.java:50:in `initialize'", "C:/logstash-7.3.2/logstash-core/lib/logstash/java_pipeline.rb:24:in `initialize'", "C:/logstash-7.3.2/logstash-core/lib/logstash/pipeline_action/create.rb:36:in `execute'", "C:/logstash-7.3.2/logstash-core/lib/logstash/agent.rb:325:in `block in converge_state'"]}

Any help and/or advice on this topic appreciated.

Tried to get schema definition to another file, co copied following:

{"type":"record","name":"Root","fields":[{"name":"id","type":["null","long"]},{"name":"info","type":["null",{"type":"record","namespace":"root","name":"Info","fields":[{"name":"first_name","type":["null","string"]},{"name":"last_name","type":["null","string"]},{"name":"address","type":["null",{"type":"record","namespace":"root.info","name":"Address","fields":[{"name":"address_street","type":["null","string"]},{"name":"address_street_num","type":["null","string"]},{"name":"address_zip_code","type":["null","long"]},{"name":"address_city","type":["null","string"]}]}]}]}]},{"name":"degree","type":["null","string"]}]}

To another file and pointed it in schema_uri parameter.
After that I am facing the following errors:
