[HELP] Displaying Syslog in color fails with an error

[axis6404]

My script for displaying syslog in color fails with an error. Can someone help me?

debian13 trixie
conky-std 1.22.1-1 amd64

Error (nothing displayed):
${color}${font Source Han Mono JP:style=Regular:size=9}${execpi 30 tail -n8 /var/log/syslog | sed 's/^.\{11\}\(.\{8\}\).\{17\}/\1/' | sed 's/\$/\$\$/g' | sed -e 's/.*ERROR.*/${color red}&${color}/Ig' -e 's/.*WARN.*/${color yellow}&${color}/Ig' -e 's/.*INFO.*/${color green}&${color}/Ig' | fold -w52 | sed 's/^/ \${voffset -3}/'}

sh: 1: Syntax error: Unterminated quoted string

Success A (removing the final sed):
${color}${font Source Han Mono JP:style=Regular:size=9}${execpi 30 tail -n8 /var/log/syslog | sed 's/^.\{11\}\(.\{8\}\).\{17\}/\1/' | sed 's/\$/\$\$/g' | sed -e 's/.*ERROR.*/${color red}&${color}/Ig' -e 's/.*WARN.*/${color yellow}&${color}/Ig' -e 's/.*INFO.*/${color green}&${color}/Ig' | fold -w52}

Success B (removing the $ sign sanitization):
${color}${font Source Han Mono JP:style=Regular:size=9}${execpi 30 tail -n8 /var/log/syslog | sed 's/^.\{11\}\(.\{8\}\).\{17\}/\1/' | sed -e 's/.*ERROR.*/${color red}&${color}/Ig' -e 's/.*WARN.*/${color yellow}&${color}/Ig' -e 's/.*INFO.*/${color green}&${color}/Ig' | fold -w52 | sed 's/^/ \${voffset -3}/'}

I solved it myself. <-It was wrong and not resolved
It seemed like the buffer for the execpi command was insufficient, so I increased it.

conky.config = {
exec_res_buffer_size = 512,
}

Sorry, but this didn't solve the problem.
With exec_res_buffer_size=512, the log is now displayed in conky. However, the command fails.
It seems the command is interrupted midway.
When I run command D, a conky_d file is created on the Desktop. This indicates that the command was interrupted halfway through.
How can I solve this?

command D:
${color}${font Source Han Mono JP:style=Regular:size=9}${execpi 30 tail -n8 /var/log/syslog|sed 's/^.\{11\}\(.\{8\}\).\{17\}/\1/'|sed 's/\$/\$\$/g' | sed -e 's/.*ERROR.*/${color red}&${color}/Ig' -e 's/.*WARN.*/${color yellow}&${color}/Ig' -e 's/.*INFO.*/${color green}&${color}/Ig'| tee /home/ad/Desktop/conky_dbg.txt | fold -w52| tee /home/ad/Desktop/cpnky_dbg2.txt | sed 's/^/ \${voffset -3}/'}
